Climate Change

"[[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%."

"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."

"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."

"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."

"[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."

"[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."

"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."

"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."

"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."

"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."

"[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."

"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."

"[I]t's . . . possible that some innovation will come along and make [other energy storage] ideas obsolete, the way the personal computer came along and more or less made the typewriter unnecessary. Cheap hydrogen could do that for storing electricity. . . . We could use electricity from a solar or wind farm to create hydrogen, store the hydrogen as a compressed gas or in another form, and then put it in a fuel cell to generate electricity on demand. [This] would solve the location problem; . . . although you can't ship sunlight in a railcar, you can turn it into fuel first and then ship it any way you like."

"Deploying today’s renewables and improving transmission couldn’t be more important. . . . Unless we use large amounts of nuclear energy . . . every path to zero {net emissions} in the United States will require us to install as much wind and solar power as we can build and find room for. It’s hard to say exactly how much of America’s electricity will come from renewables in the end, but what we do know is that between now and 2050 we have to build them much faster - on the order of 5 to 10 times faster - than we’re doing right now. And remember that most countries aren’t as lucky as the United States when it comes to solar and wind resources. The fact that we can hope to generate a large percentage of our power from renewables is the exception rather than the rule. That’s why, even as we deploy, deploy, deploy solar and wind, the world is going to need some new clean electricity inventions too."

"[W]e’re going to need much more clean electricity in the coming years. Most experts agree that as we electrify other carbon-intensive processes like making steel and running cars, the world’s electricity supply will need to double or even triple by 2050. And that doesn’t even account for population growth, or the fact that people will get richer and use more electricity. So the world will need much more than three times the electricity we generate now."

"When it comes to climate change, I know innovation isn’t the only thing we need. But we cannot keep the earth livable without it. Techno-fixes are not sufficient, but they are necessary."

"What do we need to build to fight global warming? . . . The answer is actually quite simple and requires no miracle technology: we must electrify everything, fast. That means not just the supply-side sources of energy; we’ve got to electrify everything on the demand-side - the things we use in our households and small businesses every day, including cars, furnaces, stoves, water heaters, and dryers. I’m optimistic because over the last two decades {we've made} advances and cost reductions in electric vehicles, solar cells, batteries, heat pumps, and induction cooking . . . . People who are relying on governments to solve this problem don’t understand the power they have in their own hands and homes to fight global warming. . . . One astounding thing happens when we electrify everything: we would need only one-half of the primary energy that currently powers the economy. . . . The electrification of things you do for climate is good for your health. The air in our homes will be cleaner, our cars zippier and community air quality better, our appliances faster and more high-tech, like smartphones compared to rotary phones. The electrified future can be awesome."

"In 2006, I hosted a dinner after a screening of An Inconvenient Truth, former vice president Al Gore's seminal documentary on the climate crisis. We went around the table for everyone's reaction to the film's urgent message. When it came to my fifteen-year-old daughter, Mary, she declared with her typical candor: "I'm scared, and I'm angry." Then she added, "Dad, your generation created this problem. You better fix it." . . . As a venture capitalist, my job is to find big opportunities, target big challenges, and invest in big solutions. I was best known for backing companies like Google and Amazon early on. But the environmental crisis dwarfed any challenge I'd ever seen. . . . Eugene Kleiner, the late cofounder of Kleiner Perkins . . . left behind a set of twelve laws that [included the following:] There is a time when panic is the appropriate response. That time had come. . . . My partners and I made climate a top priority. We got serious about investing in clean and sustainable technologies . . . . Our climate investments were [slow] out of the gate, and many of them failed. . . . But with patience and persistence [by 2019] our surviving cleantech investments began to hit one home run after the next. [However, we currently] have no time for a victory lap. . . . Atmospheric carbon already exceeds the upper limit for climate stability. . . . The effects of runaway global warming are already plain to see: devastating hurricanes, biblical flooding, uncontrollable wildfires, killer heat waves, and extreme droughts. . . . I must warn you up front: we're not cutting emissions fast enough to outrun the damage on our doorstep. I said this in 2007, and I say it again today: what we're doing is not nearly enough. Unless we course correct with urgent speed and at a massive scale, we'll be staring at a doomsday scenario. The melting polar ice caps will drown coastal cities. Failed crops will lead to widespread famine. By midcentury, a billion souls worldwide could be climate refugees. . . . Fortunately, we have a powerful ally in this fight: innovation. Over the past fifteen years, prices for solar and wind power have plunged 90 percent. . . . Batteries are expanding the range of electrified vehicles at an ever lower cost. Greater energy efficiency has sharply reduced greenhouse gas emissions. . . . While a good many solutions are in hand, their deployment is nowhere near where it needs to be. We'll need massive investment and robust policy to make these innovations more affordable. We need to scale the ones we have - immediately - and invent the ones we still need. In short, we need both the now and the new."

"Solving climate change should taste at least as good as carrots, at best ice cream, but it should not be painful. . . . How do we ensure the lowest cost of energy while electrifying everything? First, policymakers have to rewrite the federal, state and local rules and regulations that were created for the fossil-fueled world and which prevent the US from having the cheapest electricity ever. Our country needs to massively scale up the industrial production of technological solutions, just as we did to win World War II. We cannot take our foot off the innovation gas - although I'll argue that we don't need any major breakthroughs, as thousands of little inventions and cost reductions are the key to achieving our end goal. Finally, we must have cheap financing for our transition to a zero-carbon energy system with low-interest "climate loans." Climate change will not be solved if only the richest 10% can afford it; we need mechanisms to bring everyone along for the ride."

"Future Outlook: Global offshore wind energy deployment is expected to accelerate in the future, with forecasts from 4C Offshore and Bloomberg New Energy Finance indicating a sevenfold increase in global cumulative offshore wind capacity - to 215 [gigawatts] or more by 2030 (BNEF 2020; 4C Offshore 2021). As part of that predicted surge, the U.S. offshore wind energy market continues to expand, primarily driven by increasing state-level procurement targets in the Northeast and mid-Atlantic, an increased number of projects clearing major permitting milestones, as well as growing vessel, port, and infrastructure investments needed to keep pace with development."

"There’s one aspect of the current fleet of magnetic fusion machines that is holding back progress. It’s a lesson that has been learned time and time again in fusion: . . . fusion works best on big scales. For conventional tokamaks, the confinement of plasma gets better the bigger the machine is. . . . When it is completed, ITER will be the world’s largest tokamak, and one of its key objectives will be to demonstrate net energy gain. It’s a behemoth. . . . ITER will take up 180 hectares (equivalent to 250 soccer fields), and when finished, its structure will have a mass equivalent to three Eiffel Towers."

"There are two practical ways to create the magic conditions that make fusion happen. One is called magnetic confinement fusion and the other is inertial confinement fusion. There’s gravity too, of course, but for that you need scales bigger than can be created on Earth: you need, quite literally, a star. The magnetic approach is to bind the hot matter in a reactor with an invisible web of magnetic fields. The inertial approach sets matter crashing into itself, thereby both heating and compressing it, and aims to get all the fusion done before the assembled star matter falls apart again. NIF {the National Ignition Facility} uses lasers to do this."

"An old proverb states: When the winds of change blow, some build walls . . . others build windmills. So, fellow windmill builders: Let’s push back on doubt and fear. Climate disasters worldwide tell us that the scariest thing we could do is nothing at all. . . . [W]e’ll all gain when we succeed - starting with jobs! We’re looking at a $23 trillion global market in the clean energy transition by 2030. . . . That means we can remake our economies, build new businesses, and put millions upon millions of people to work. . . . For too long, the climate conversation has been viewed as a zero-sum game. One of trade-offs: the climate or the economy. No longer."

"I think it’s clear now that energy has to be clean. . . . And we should do it in ways that give jobs to everybody. . . . There’s so much to do in renewable power, there is so little to do in coal."

"[N]ew renewable power generation projects now increasingly undercut existing coal-fired plants. On average, new solar photovoltaic (PV) and onshore wind power cost less than keeping many existing coal plants in operation, and auction results show this trend accelerating – reinforcing the case to phase-out coal entirely."

"The clean energy portfolios of some of the largest corporate buyers rival those of the world’s biggest utilities. These companies are facing mounting pressure from investors to decarbonize - clean energy contracts serve as a way to diversify energy spend and reduce susceptibility to the tangible risks associated with climate change."

"Offshore wind is in a category of its own, as the only variable baseload power generation technology. . . . Offshore wind output . . . hourly variability is lower than that of solar [photovoltaics]. Offshore wind typically fluctuates within a narrower band, up to 20% from hour-to-hour, than is the case for solar [photovoltaics], up to 40% from hour-to-hour."

"Offshore wind's remarkable potential: The global offshore wind market grew nearly 30% per year between 2010 and 2018, benefitting from rapid technology improvements and about 150 new offshore wind projects . . . in active development around the world. . . . Yet today's offshore wind market doesn't even come close to tapping the full potential - with high-quality resources available in most major markets, offshore wind has the potential to generate more than 420,000 [terawatt-hours] per year worldwide. This is more than 18 times global electricity demand today."

"A carbon tax offers the most cost-effective lever to reduce carbon emissions at the scale and speed that is necessary. By correcting a well-known market failure, a carbon tax will send a powerful price signal that harnesses the invisible hand of the marketplace to steer economic actors towards a low-carbon future. . . . A consistently rising carbon price will encourage technological innovation and large-scale infrastructure development."

"The transition to renewable energy can be greatly accelerated if the world’s governments finally bring the engineers to the fore... I was recently on a panel with three economists and a senior business-sector engineer. After the economists spoke... the engineer spoke succinctly and wisely. “I don’t really understand what you economists were just speaking about, but I do have a suggestion... Tell us engineers the desired ‘specs’ and the timeline, and we’ll get the job done.” This is not bravado.... The next big act belongs to the engineers. Energy transformation for climate safety is our twenty-first-century moonshot."

"[W]ind and solar power have been rapidly winning market acceptance. Last year, the installed capacity of solar power in the United States nearly doubled. And wind is now being harnessed to produce 5.5 percent of America’s electricity, according to the U.S. Energy Information Administration."

"Rather than an eyesore on the roof, it becomes actually a feature of the home. People are going to start wanting to put {building-integrated photovoltaics} on the front side of their home to show that they have solar."

"We have long supported a carbon tax as the best policy of those being considered. Replacing the hodge-podge of current, largely ineffective regulations with a revenue-neutral carbon tax would ensure a uniform and predictable cost of carbon across the economy. It would allow market forces to drive solutions. It would maximize transparency, reduce administrative complexity, promote global participation and easily adjust to future developments in our understanding of climate science as well as the policy consequences of these actions."

"Cheaper coal and cheaper gas will not derail the transformation and decarbonisation of the world’s power systems. By 2040, zero-emission energy sources will make up 60% of installed capacity."

"If you told me that innovation had been frozen and we just have today's technologies, will the world run the climate change experiment? You bet we will. We will not deny India coal plants; we will run the scary experiment of heating up the atmosphere and seeing what happens. The only reason I'm optimistic about this problem is because of innovation. . . . I want to tilt the odds in our favor by driving innovation at an unnaturally high pace, or more than its current business-as-usual course. I see that as the only thing. I want to call up India someday and say, "Here's a source of energy that is cheaper than your coal plants, and by the way, from a global pollution and local pollution point of view, it's also better.""

"The only way you can get to the very positive scenario is by great innovation. Innovation really does bend the curve."

"One of the real breakthroughs is when someone figures out long-term storage capacity."

"Every percentage point increase in homegrown renewable energy makes us that much more energy secure. The progress in electricity is encouraging, but growth is not yet strong enough in renewable heat and transport to meet the government's objectives."

"Renewable energy: dumbest phrase since climate change. See the first law of thermodynamics, dumbass."

"More solar energy falls on Earth in one hour than all the energy our civilization consumes in an entire year. If we could harness a tiny fraction of the available solar and wind power, we could supply all our energy needs forever, and without adding any carbon to the atmosphere."

"[The] solar-energy firm known as Solyndra, which the [[w:United_States_Department_of_Energy|[US] Energy Department]] had backed with a $535 million loan guarantee [made the] unexpected announcement last week that it is filing for bankruptcy, leaving hundreds of workers jobless - and taxpayers on the hook for almost all of its government-backed loan. . . . [I]t’s not too early to draw some policy lessons from Solyndra’s ignominious downfall. . . . [G]overnment is no better than the private sector at picking industrial winners - and usually worse. . . . To the extent that government creates jobs by subsidizing particular companies, it does so by shifting resources that might have created jobs elsewhere. Political favoritism, or the appearance thereof, is an inherent risk . . . . When "green jobs" promises don’t pan out, it does the environmental cause more harm than good."

"There is one forecast of which you can already be sure: someday renewable energy will be the only way for people to satisfy their energy needs. Because of the physical, ecological and (therefore) social limits to nuclear and fossil energy use, ultimately nobody will be able to circumvent renewable energy as the solution, even if it turns out to be everybody’s last remaining choice. The question keeping everyone in suspense, however, is whether we shall succeed in making this radical change of energy platforms happen early enough to spare the world irreversible ecological mutilation and political and economic catastrophe."

"Although photosynthesis typically has an energy conversion efficiency below three percent, it is, together with heat from the sun, the main energy source of all living organisms, and the energy source from which biomass and fossil fuels are derived. Each year the earth receives an energy input from the sun equal to 15,000 times the world's commercial energy consumption and 100 times the world's proven coal, gas and oil reserves."

"I'd put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that."

"We need to address climate change, we need to limit the temperature rise globally to the maximum extent but we cannot do it at the expense of keeping people in poverty and stopping their economic development."

"Our nation has eight million jobs in clean energy! Can we double it, guys, before the sea levels rise And I'm roommates with a manatee?"

"We need to do more research to really try and understand what’s going on here. Is this also a sign of climate change or did British Columbia just get incredibly unlucky this year?"

"Man has reached the point where his impact on the climate can be as significant as [the rest of] nature's."

"It is worse, much worse, than you think. The slowness of climate change is a fairy tale, perhaps as pernicious as the one that says it isn’t happening at all, and comes to us bundled with several others in an anthology of comforting delusions: that global warming is an Arctic saga, unfolding remotely; that it is strictly a matter of sea level and coastlines, not an enveloping crisis sparing no place and leaving no life undeformed; that it is a crisis of the “natural” world, not the human one; that those two are distinct, and that we live today somehow outside or beyond or at the very least defended against nature, not inescapably within and literally overwhelmed by it; that wealth can be a shield against the ravages of warming; that the burning of fossil fuels is the price of continued economic growth; that growth, and the technology it produces, will allow us to engineer our way out of environmental disaster; that there is any analogue to the scale or scope of this threat, in the long span of human history, that might give us confidence in staring it down."

"Because the numbers are so small, we tend to trivialize the differences between one degree and two, two degrees and four. Human experience and memory offers no good analogy for how we should think about those thresholds, but with degrees of warming, as with world wars or recurrences of cancer, you don’t want to see even one."
