Environmentalism

"Over the past decade, installed wind capacity has grown by an average of 20 percent a year, and wind turbines now provide about 5 percent of the world's electricity. Wind is growing for one simple reason: It's getting cheaper."

"[W]e [must] make this COP 26 in Glasgow the moment when we get real about climate change, and we can. We can get real on coal, cars, cash and trees. . . . But we cannot and will not succeed by government spending alone. . . . [T]he task now is to work together to help our friends to decarbonise using . . . the funds we have in development assistance and working with all the multilateral development banks so that in the key countries that need to make progress, we can jointly identify the projects that we can help to de-risk so that the private sector money can come in . . . . [Let us] in the next days devote ourselves to this extraordinary task. So that we not only continue with . . . a green industrial revolution, that is already creating millions of high wage, high skill jobs in power and technology, taking our economies forward. Let us also do enough to save our planet and our way of life."

"Climate change and biodiversity loss . . . pose an even greater existential threat [than the COVID-19 pandemic], to the extent that we have to put ourselves on what might be called a war-like footing. . . . Putting a value on carbon . . . [is] absolutely critical. . . . [W]e need a vast military style campaign to marshall the strength of the global private sector[, which has] trillions at its disposal . . . . [E]ach sector needs a clear strategy to speed up the process of getting innovations to market [and we] need to align private investment behind these industry strategies. . . . If we can develop a pipeline of many more sustainable and "bankable" projects, at a sufficient scale, it will attract greater investment. . . . CEOs and institutional investors have told me that alongside the promises countries have made, their nationally determined contributions, they need clear market signals, agreed globally, so that they have the confidence to invest without the goal posts suddenly moving. . . . [[w:Charles, Prince of Wales#Natural environment|[W]e are working]] to drive trillions of dollars in support of transition across ten of the most emitting and polluting industries [including] energy, agriculture, transportation, health systems and fashion. . . . I can only urge you, as the world’s decision-makers, to find practical ways of overcoming differences so we can all . . . rescue this precious planet and save the threatened future of our young people."

"Climate change is already . . . costing our nations trillions of dollars [and] we know that none of us can escape the worst that’s yet to come if we fail to seize this moment. . . . But . . . within the growing catastrophe, I believe there’s an incredible opportunity . . . . We have the ability to invest in ourselves and build an equitable clean-energy future and in the process create millions of good-paying jobs [while we] create an environment that raises the standard of living around the world. . . . When I talk to the American people about climate change, I tell them it’s about jobs. It’s about workers [and the] communities that will revitalize themselves around new industries and opportunities. . . . So, let’s get to work."

"We are aware that the industrialised countries have a particular responsibility. . . . The financing is essential if the industrialised countries are to maintain their credibility. . . . Ladies and gentlemen, with government activities alone we will not make progress. For this requires radical transformation of how we live, work and conduct business. I therefore want to take this opportunity to make a very clear appeal for pricing for CO2 emissions. With this form of pricing, which we already have in the European Union, which is to be introduced in China and which needs to be developed together with many others throughout the world, we could get our industries and businesses to find the technologically most effective and efficient ways to achieve climate neutrality. We need to work out how we can best integrate CO2-free mobility, CO2-free industry and CO2-free processes into our lives. My clear call in the Decade of Action, in the decade in which we now live, is for us to become more ambitious at a national level and at the same time to find global instruments that not only make use of taxpayers’ money but are also economically viable. And for me, the answer is CO2 pricing."

"In the midst of this global brainstorming on climate change, on behalf of India, I would like to present five [commitments] to deal with this challenge. First - India will take its non-fossil energy capacity to 500 gigawatts by 2030. Second - India will meet 50 percent of its energy requirements from renewable energy by 2030. . . . And fifth - by the year 2070, India will achieve the target of Net Zero. . . . Today, when India has resolved to move forward with a new commitment and a new energy, the transfer of climate finance and low cost climate technologies have become more important. . . . India also understands the suffering of all other developing countries, shares them, and will continue to express their expectations."

"India is pioneering a new model of economic development that could avoid the carbon-intensive approaches that many countries have pursued in the past - and provide a blueprint for other developing economies. . . . {India's} economic growth has been among the highest in the world over the past two decades {as coal} and oil have so far served as bedrocks of India’s industrial growth and modernisation . . . . India’s annual CO2 emissions have risen to become the third highest in the world {but} India’s CO2 emissions per person put it near the bottom of the world’s emitters . . . India’s sheer size and its huge scope for growth means that its energy demand is set to grow by more than that of any other country in the coming decades. . . . {T}he good news is that the clean energy transition in India is already well underway. . . . Subsidies for petrol and diesel were removed in the early 2010s, and subsidies for electric vehicles were introduced in 2019. . . . {The country is} laying the groundwork to scale up important emerging technologies such as hydrogen, battery storage, and low-carbon steel, cement and fertilisers. . . . A transition to clean energy is a huge economic opportunity {but support} from the international community is essential to help shift India’s development onto a low-carbon path {and} access of low cost long term capital is key to achieve net zero. . . . India aims to become a global hub for green hydrogen production and exports. . . . As a large developing economy with over 1.3 billion people, India’s climate adaptation and mitigation ambitions are not just transformational for India but for the entire planet."

"[T]he solution has to be real economy government regulations to ban or to make higher [the] cost of the brown and polluting industries. That said, there are parts of finance which are longer-term and [evaluate] climate risks . . . and these are asset owners, the pension funds, the wealth funds and the insurance companies who are not so transactional [and] they’re not [as] interested in a deal to be done today. And they are in fact often mandated by their governments to take into account climate risk. So, I think those players will step up in this instance [turmoil in energy markets following Russia's 2022 invasion of Ukraine] and [now who might be] investing for [an electricity generation project with a] 10-year horizon which you have to do with gas they will [say], "Let’s do it with renewables." And we’ve seen movements like that in the UK, where they’re pivoting towards onshore wind, which before the invasion was politically unviable because of the NIMBY factor. . . . [T]he pension funds and the actual asset owners . . . have a longer term of perspective. And they are actually driving the issue to their commercial managers who have to service them and they’re saying, "Look, we want you to act on climate change," and that's a huge driver."

"[A]s an atmospheric scientist and environmental engineer, I focus most on technologies — that’s what we think about most of what we need to be able to clean up electricity, what we need for cleaner cars. But those aren’t going to make it to market and those aren’t going to help cool the climate unless there are policies that get those to be deployed domestically. And what we do domestically isn’t enough because we’re only 1/7th of the world’s emissions, so we need diplomacy to take what we do here in the U.S. and make sure that that starts being applied in other parts of the world as well. . . . [A]s I was looking at the diplomacy [I noticed that what] the United States really gets right is being reciprocal . . . when we do something, we usually insist that our trading partners go along as well. You even hear in Congress talk about if we ever did have a carbon tax, being sure it got applied as tariffs on goods that got brought in."

"Solar has plunged by 90% in cost. Wind has plunged by 80% just in the past 11 or 12 years. . . . Things like wind and solar power really can already out-compete dirtier forms of electricity, and we just need to build more of them quickly; we’re not adding them fast enough. There are other technologies where we really need a big breakthrough. We don’t yet have affordable enough heat pumps. We don’t yet have a next generation nuclear technology that’s cheap enough, if we ever will. Geothermal is really at the cusp of becoming something that I think could really take off. What I also see, though, is that what carries those cutting-edge technologies to the cheaper cost can’t just happen in the lab. We need policies that pull those into the market, that get them adopted more — because if we can adopt them while they’re at that edge; while they’re not quite cheap enough, that can drive the economies of scale; that can drive what technologists call learning by doing."

"The ability to use renewables for the lion’s share of a grid’s supply, coupled with the fact that renewables have been made cheap and are getting yet cheaper, is the basis of a decarbonisation strategy all but universally accepted by those determined to stabilise the climate. Make the power on electric grids emissions-free, cheap and copious. Start electrifying all processes that now require fossil fuels - such as powering cars, or heating homes and steel foundries - where electrification is clearly possible. It does not deliver everything that is needed. But it delivers a lot."

"Even if you're a climate denier, you should be on board with what we're advocating. . . . Our central conclusion is that we should go full speed ahead with the green energy transition because it's going to save us money."

"[[w:Energy storage#Chemical|[Storing energy using] hydrogen]] . . . is getting a lot of play now. You could burn hydrogen in a gas turbine to produce electricity. You could use hydrogen in fuel cells that produce electricity without combustion; still a chemical reaction. Or you could simply use hydrogen to create ammonia, NH3, which is another liquid, as opposed to gaseous, chemical storage medium. . . . [E]xperts say that we could probably convert the grid 80% to renewable - that's wind and solar - without having to deal with [the] long-duration storage problem. We'd still use gas peaker plants for . . . 20% of the electricity that we need. If you want to do the other 20%, you're going to have to solve that problem of . . . long-term storage for the grid, days in a row. And you could do that with gravity storage. You could do that with a chemical energy carrier. It's done with methane now. So we've got to get rid of the methane. But you could have hydrogen or ammonia or another chemical energy medium which is yet to be discovered. That's the challenge. We can get to 80%, but we can't get to 100%."

"The global energy crisis is driving a sharp acceleration in installations of renewable power, with total capacity growth worldwide set to almost double in the next five years, overtaking coal as the largest source of electricity generation along the way and helping keep alive the possibility of limiting global warming to 1.5 °C . . . . Global renewable power capacity is now expected to grow by 2,400 gigawatts (GW) over the 2022-2027 period, an amount equal to the entire power capacity of China today, according to Renewables 2022, the latest edition of the IEA {International Energy Agency}’s annual report on the sector. . . . The amount of renewable power capacity added in Europe in the 2022-27 period is forecast to be twice as high as in the previous five-year period, driven by a combination of energy security concerns and climate ambitions. . . . Beyond Europe, the upward revision in renewable power growth for the next five years is also driven by China, the United States and India, which are all implementing policies and introducing regulatory and market reforms more quickly than previously planned to combat the energy crisis. . . . China is expected to account for almost half of new global renewable power capacity additions over the 2022-2027 period. Meanwhile, the US Inflation Reduction Act has provided new support and long-term visibility for the expansion of renewables in the United States. . . . Utility-scale solar PV [photovoltaics] and onshore wind are the cheapest options for new electricity generation in a significant majority of countries worldwide. Global solar PV capacity is set to almost triple over the 2022-2027 period, surpassing coal and becoming the largest source of power capacity in the world. The report also forecasts an acceleration of installations of solar panels on residential and commercial rooftops . . . . Global wind capacity almost doubles in the forecast period, with offshore projects accounting for one-fifth of the growth. Together, wind and solar will account for over 90% of the renewable power capacity that is added over the next five years. . . . While China remains the dominant player [in photovoltaic supply chains], its share in global manufacturing capacity could decrease from 90% today to 75% by 2027. . . . Total global biofuel demand is set to expand by 22% over the 2022-2027 period. . . . In advanced economies . . . faster growth [in renewable power capacity] would require various regulatory and permitting challenges to be tackled and a more rapid penetration of renewable electricity in the heating and transport sectors. In emerging and developing economies, [faster growth] would mean addressing policy and regulatory uncertainties, weak grid infrastructure and a lack of access to affordable financing that are hampering new projects. . . . Worldwide, the accelerated case requires efforts to resolve supply chain issues, expand grids and deploy more flexibility resources to securely manage larger shares of variable renewables. The accelerated case’s faster renewables growth would move the world closer to a pathway consistent with reaching net zero emissions by 2050, which offers an even chance of limiting global warming to 1.5 °C."

"We have taken the first tentative steps towards a clean energy source that could revolutionize the world."

"Offshore wind turbines reach even higher and wider than land-based ones. Though twice as expensive as land-based wind, their costs are falling fast. That’s making offshore wind increasingly attractive in coastal regions of Europe and the northeastern United States, where population density is high, land is scarce, and winds over the ocean far outpace those over land."

"[W]e’ll never build enough batteries to back up the grid. Batteries are costly to build and costly to operate, since energy is dissipated each time they are charged and discharged. Transmission moves power more efficiently. Complementary resources smooth out supply. Demand flexibility narrows gaps and surpluses between supply and demand. The more robustly we deploy complementary resources, transmission, and flexibility, the less storage we will need to build and the less often we will have to deploy it, reducing the overall costs of electricity."

"[[w:Hydrogen economy|[H]ydrogen has many potential uses]], including electricity storage, trucking, chemical production, and industrial heat - which means options for producing and distributing hydrogen deserve a closer look. "Hydrogen is hard to make, hard to move, and hard to store, but once you’ve got it, it is a brilliant ingredient," [[w:Michael Webber|[Professor Michael] Webber]] told me."

"The [provisions of the proposed Inflation Reduction Act of 2022, including] expansion of the wind and solar credits, the exciting expansion, or creation, of additional credits in green hydrogen, the inclusion of hydrogen cars in electric car credits, the extension of the electric car credits - all those things are good [but they're] not enough. The question now is, what do we do next?"

"The Inflation Reduction Act calls for spending less than $500 billion over a decade, compared with the American Rescue Plan’s $1.9 trillion in a single year . . . . But if the spending isn’t very large, how can it have such a big impact? The answer is that right now we’re sitting on a sort of cusp. Renewable energy technology has made revolutionary progress, and renewables are already cheaper in many areas than fossil fuels. A moderate push from public policy is all that it will take to transition to a much greener economy. And the Inflation Reduction Act will provide that push."

"[The Inflation Reduction Act] . . . doesn’t solve the climate challenge. This is the beginning . . . and the implementation is going to be everything. This is . . . like a starting gun for a race that's going to . . . hopefully define the coming decade of building something better."

"I’m about to sign the Inflation Reduction Act into law . . . . The [climate component of this legislation] invests $369 billion to take the most aggressive action ever . . . in confronting the climate crisis and strengthening . . . our energy security."

"{The US Inflation Reduction Act of 2022} is really good for a developing economy like Indonesia due to spillover effects because of lower costs {for technologies that help mitigate climate change}."

"[T]he analogy [regarding the three recent US climate laws] we’ve been thinking about is the backbone, the brain, and the lungs. So, the backbone being the Bipartisan Infrastructure Law {November 2021} . . . . That law [includes] investment in US infrastructure [such as] roads and bridges, but including significant energy infrastructure. Then there's the brain, the CHIPS and Science Act {August 2022}, and chips being the semiconductors that are in {electric vehicles, energy infrastructure, etc.} . . . and the science part authorizes additional investments from Congress in science {related to grid upgrades, zero emissions research, etc. by the} National Science Foundation and DOE {Department of Energy}. And then the third piece is the lungs. So, [taking a deep breath] breathing into that clean energy economy, the Inflation Reduction Act {August 2022} incentivizes deployment of clean technologies and really focuses on lowering costs for American families."

"Great, that is fantastic . . . . We want to be able to see energy - clean energy - produced in every pocket of the country. Blue states, red states, really it helps to save people money, so it’s all about green."

"[[w:Climate change policy of the United States#Federal policy|[I]f you think about how many times [US] politicians have tried and failed to pass climate legislation]], it's really notable that the Inflation Reduction Act went through. So in the past, basically legislators tried to have sticks: . . . there would be a cap and trade bill; people had debated a carbon tax. The Inflation Reduction Act includes no sticks, it's only carrots. . . . [T]his law is kind of a complicated way to try to go about decarbonizing America, but it proved to be the only politically viable option that American politicians had yet come up with. And so, I think, on those terms, it's absolutely a victory . . . for those who were trying to advance some kind of climate legislation through Washington."

"Climate security goes hand in hand with energy security. Putin’s abhorrent war in Ukraine and rising energy prices across the world are not a reason to go slow on climate change. They are a reason to act faster. Because diversifying our energy supplies by investing in renewables is precisely the way to insure ourselves against the risks of energy dependency. It is also a fantastic source of new jobs and growth."

"[COP27] ended on Sunday morning with researchers largely frustrated at the lack of any ambition to phase out fossil fuels. However, there was one silver lining: delegates from low and middle income countries (LMICs) came away with an agreement on a new 'loss and damage' fund to help them cover the costs of climate-change impacts. . . . Many blamed the energy crisis sparked by Russia’s invasion of Ukraine for a lack of progress on fossil fuels."

"[T]he change we need is to put innovation at the heart of everything we do. . . . [M]ajor challenges like energy security and net zero will be solved by innovation. The more we innovate, the more we grow."

"India has to do it for itself. . . . And India needs to do it for the world."

"Last year was a double milestone for decarbonizing the world’s energy system. It was the first year when investment in the energy transition equaled global investment in fossil fuels . . . . [And] 2022 was . . . the first year when investment in decarbonizing energy surpassed $1 trillion. The year-on-year increase of more than $250 billion from 2021 was the largest jump yet."

"[T]he process for the permitting of renewable energy generation and electric transmission projects in the United States is multi-layered and often extremely long. If the U.S. is to achieve its climate ambitions and fully implement transformative legislation like the Inflation Reduction Act, Congress will also have to enable a massively accelerated build-out of clean energy infrastructure. At the same time, valuable environmental safeguards, and the established public participatory and related administrative processes used to adopt and implement them, cannot simply be sidestepped. Congress should approach federal permitting reform in a way that maximizes efficiency in government decisionmaking through shorter timelines for regulatory approvals without sacrificing the value of the current process in protecting the environment and local stakeholders. Further, it is essential that reforms are evidence-based in targeting the major sources of current delays."

"Because Australia has {aggressively incentivized adoption of} rooftop solar, the economics are extraordinary. . . . So if we use our cheap sunshine to drive our cars and heat our homes, we're going to save money sooner."

"In the last several months all the key associations looked across the table and realised we were arguing for the same thing. . . . This is Big Wind and Big Solar coming to the table and saying we want to get things done. . . . It will not be possible to achieve anything close to a climate solution with the current {permitting} system in place."

"{H}ydrogen is seen as a way to substitute large amounts of energy that we’re buying now at extremely high costs from countries that we shouldn’t buy this from."

"And it's just the beginning. You know, we also protected the most significant breakthrough ever—ever—in dealing with the existential threat of climate change. Today, new wind and solar power is cheaper than fossil fuel. Since I've been in office, clean energy and advanced manufacturing have brought in $470 billion in private investments. That's going to create thousands of jobs—good-paying jobs—all across this country and help the environment at the same time. And remember, at the beginning of this debate, some of my Republican colleagues were determined to gut the clean energy investments. And I said no, and we kept them all."

"We have a tremendous sense of pride in our history . . . But we also understand that energy is energy, whether it is generated by wind, steam or whatever it might be."

"Solar energy is the most widely available energy resource on Earth, and its economic attractiveness is improving fast in a cycle of increasing investments. . . . [D]ue to technological trajectories set in motion by past policy, a global irreversible solar tipping point may have passed where solar energy gradually comes to dominate global electricity markets, without any further climate policies. Uncertainties arise, however, over grid stability in a renewables-dominated power system, the availability of sufficient finance in underdeveloped economies, the capacity of supply chains and political resistance from regions that lose employment."

"{T}he challenges are great but we have the conviction that by working together - the {European} Commission, the ITER Organization and F4E {Fusion for Energy} - we can overcome them and slowly but steadily bring the ITER project back on its rails."

"Electricity generation. We expect that the 23 gigawatts (GW) in 2023 and 37 GW in 2024 of new solar capacity scheduled to come online will help U.S. solar generation grow by 15% in 2023 and by 39% in 2024. We expect solar and wind generation together in 2024 to overtake electric power generation from coal for the first year ever, exceeding coal by nearly 90 billion kilowatthours."

"We're not interested in a pilot [climate project] just for experimentation. . . . We're interested in proving that they work and that then we can scale them. . . . Utilities [can't afford to] move fast and break things [but they] can be great mechanisms for scaling up innovation."

"I think [it’s] to be determined {whether the post-pandemic, low-interest-rate-fueled investment spike which flowed to non-governmental fusion companies will actually result in commercially viable fusion power}. . . . When interest rates were low, people were willing to make long-term bets. [However, the] level of investment was substantial, and it should yield technological progress."

"If the world is to decarbonise, then more clean energy is needed, fast. [To meet current UNFCCC pledges, countries must] raise global renewable-energy capacity to 11,000 gigawatts (GW) by 2030. [However, supply chain problems and rising interest rates cloud the industry's future. Another obstacle is slow permitting] approval, which delays projects for years and can needlessly tie up capital, lowering returns. [And,] too little development is happening in the global south [because investors require a premium when venturing money in emerging markets]. A last obstacle is protectionism, which raises costs and threatens shortages. . . . Rather than micromanaging production, governments should unleash investment, by acting boldly to strip back permitting rules and ease the risk of projects in the global south [which can come from blending in government money in southern projects that assumes some risk]. They also need to face up to the fact that protectionism frustrates their climate goals. It leads to lower returns, higher prices for power and more broken promises over decarbonisation."

"[D]ata from the World Meteorological Agency show that, as the U.N. Secretary-General, António Guterres, told the {COP28} global climate talks in Dubai last week, we can safely say, even with weeks to go, that 2023 will take the title {as the world's hottest year on record}. . . . And yet . . . [a]lmost simultaneous with the breakout in temperature, there was a breakout in the installation of renewable energy, especially solar power, around the world. . . . {T}he cost of clean energy has dropped so far that it is now possible that saving the planet might be a corollary of saving cash. This ongoing drop in price is more than a decade old, but sometime in the past few years it crossed an invisible line, making it cheaper than hydrocarbons, and this was the year when that reality finally translated into dramatic action on the ground. . . . There are plenty of other technologies we’re [currently] spending money on, including small nuclear reactors and giant carbon-sucking machines, that may or may not someday play a role in the climate fight, but, for all the furor they produce, they seem unlikely to make much difference anytime soon. In the next few years, while the planet’s climate system teeters on the edge of breaking, it’s sun, wind, and batteries that matter. They’re cheap, and they’re ready."

"{In 2023 it was the clean economy expansion efforts of} China that blew everyone away. In what may be the single biggest sustainability headline of the year, China’s national oil company, Sinopec, said the country had reached peak gasoline demand (in part by radically increasing sales of EVs). Some analysts believe China may have peaked in total carbon emissions already. The country was on track to add 150 gigawatts of solar this year (versus adding 87 gigawatts in 2022), more than the total capacity in the U.S. And in a rare positive moment in U.S.-China relations, the countries agreed to ramp up renewables. If all the estimates are true, it’s a monumental and fundamental shift in global energy and transportation systems . . . . On the other hand . . . As critics point out, China is permitting more coal plants, but this can get misconstrued. (People say to me that China is building two plants per week when, in reality, many don’t get built.) The new plants are much cleaner, it’s generally backup power, and China is also cancelling and shelving plants rapidly as well."

"It is often heard . . . that efforts to mitigate climate change by reducing the use of fossil fuels and developing cleaner energy sources will lead to a reduction in the number of jobs. What is happening is that millions of people are losing their jobs due to different effects of climate change: rising sea levels, droughts and other phenomena affecting the planet have left many people adrift. Conversely, the transition to renewable forms of energy, properly managed, as well as efforts to adapt to the damage caused by climate change, are capable of generating countless jobs in different sectors. This demands that politicians and business leaders should even now be concerning themselves with it."

"We are edging ever-closer to a fusion-powered reality. And at the same time, yes, significant scientific and engineering challenges exist. . . . Careful thought and thoughtful policy is going to be critical to navigate this."

"{UNFCCC participant countries should transition} away from fossil fuels in energy systems, in a just, orderly and equitable manner, accelerating action in this critical decade, so as to achieve net zero by 2050 in keeping with the science[; they should also accelerate] efforts towards the phase-down of unabated coal power[; and triple] renewable energy capacity globally."

"No, the Cop28 agreement will not enable the world to hold the 1.5C limit, but yes, the result is a pivotal landmark. This agreement delivers on making it clear to all financial institutions, businesses and societies that we are now finally – eight years behind the Paris schedule – at the true "beginning of the end" of the fossil fuel-driven world economy."

"Tripling {global renewable energy capacity} is a monumental change. . . . We don't have any structures that fit 100% with the new system that is coming."
