"With global electricity demand set to grow strongly, new technologies {like enhanced geothermal systems and closed-loop geothermal systems} are opening up the massive potential of geothermal energy to provide around-the-clock clean power in almost all countries around the world, according to a new IEA report. The report, The Future of Geothermal Energy, finds that geothermal energy could meet 15% of global electricity demand growth between now and 2050 if project costs continue to decline. This would mean . . . delivering annual output equivalent to the current electricity demand of the United States and India combined. . . . Importantly, geothermal energy can draw upon the expertise of today’s oil and gas industries by using existing drilling techniques and equipment to go deeper under the earth’s surface . . . . Conventional geothermal remains a location-specific, niche technology today with most of the installed capacity in countries that have either volcanic activity or straddle tectonic fault lines . . . . But new technologies are . . . opening up the potential to benefit from it in nearly all countries. . . . [T]he report finds that costs could fall by 80% by 2035 to around $50 per megawatt hour (MWh). This would make geothermal the cheapest source of dispatchable low-emissions electricity on a par with existing hydropower and nuclear installations. . . . If next-generation geothermal grows strongly in the coming years, employment in the overall geothermal sector could increase sixfold to 1 million jobs by 2030 . . . . Up to 80% of the investment required in geothermal involves capacity and skills that are transferrable from existing oil and gas operations. The oil and gas industry can also benefit {because next-generation geothermal can} serve as a hedge against commercial risks related to projected future declines in oil and gas demand. At a time when the digital economy and artificial intelligence applications are growing strongly {and with} next-generation geothermal offering a stable and essentially inexhaustible power source, large technology companies are already signing power purchase agreements with new projects."

"[1] 2023 saw a step change in renewable capacity additions, driven by China’s solar PV market. Global annual renewable capacity additions increased by almost 50% to nearly 510 gigawatts (GW) in 2023, the fastest growth rate in the past two decades. . . . [2] Achieving the COP28 target of tripling global renewable capacity by 2030 hinges on policy implementation. . . . [C]hallenges [that could prevent reaching the tripling goal] fall into four main categories and differ by country: 1) policy uncertainties and delayed policy responses to the new macroeconomic environment; 2) insufficient investment in grid infrastructure preventing faster expansion of renewables; 3) cumbersome administrative barriers and permitting procedures and social acceptance issues; 4) insufficient financing in emerging and developing economies. . . . [3] The global power mix will be transformed by 2028. . . . In 2028, renewable energy sources [are expected to] account for over 42% of global electricity generation, with the share of wind and solar PV doubling to 25%. . . . [4] China is the world’s renewables powerhouse. . . . China’s role is critical in reaching the global goal of tripling renewables because the country is expected to install more than half of the new capacity required globally by 2030. . . . [5] The US, the EU, India and Brazil remain bright spots for onshore wind and solar PV growth. . . . Supportive policy environments and the improving economic attractiveness of solar PV and onshore wind are the primary drivers behind this acceleration. . . . [6] Solar PV prices plummet amid growing supply glut. . . . Despite unprecedented PV manufacturing expansion in the United States and India driven by policy support, China is expected to maintain its 80‑95% share of global supply chains . . . . [7] Onshore wind and solar PV are cheaper than both new and existing fossil fuel plants. . . . Despite the increasing contribution needs for flexibility and reliability to integrate variable renewables, the overall competitiveness of onshore wind and solar PV changes only slightly by 2028 in Europe, China, India and the United States. . . . [8] The new macroeconomic environment presents further challenges that policy makers need to address. . . . Since 2022, central bank base interest rates have increased from below 1% to almost 5%. . . . The implications . . . are manifold . . . . [I]nflation has increased equipment costs . . . [H]igher interest rates are increasing the financing costs of capital-intensive variable renewable technologies. . . . [And] policy has been relatively slow to adjust to the new macroeconomic environment due in part to expectations that cost reductions would continue . . . . [9] The forecast for wind capacity additions is less optimistic outside China, especially for offshore. . . .The wind industry, especially in Europe and North America, is facing challenges due to a combination of ongoing supply chain disruptions, higher costs and long permitting timelines. . . . [10] Faster deployment of variable renewables increases integration and infrastructure challenges. . . . Although European Union interconnections help integrate solar PV and wind generation, grid bottlenecks will pose significant challenges and lead to increased curtailment in many countries as grid expansion cannot keep pace with accelerated installation of variable renewables. . . . [11] Current hydrogen plans and implementation don’t match. . . . We have revised down our forecasts for all regions except China. The main reason is the slow pace of bringing planned projects to final investment decisions due to a lack of off‑takers and the impact of higher prices on production costs. . . . [12] Biofuel deployment is accelerating and diversifying more into renewable diesel and biojet fuel. . . . Emerging economies, led by Brazil, dominate global biofuel expansion . . . . Biofuels remain the dominant pathway for avoiding oil demand in the diesel and jet fuel segments. EVs outpace biofuels in the gasoline segment, especially in the United States, Europe and China. . . . [13] Aligning biofuels with a net zero pathway requires a huge increase in the pace of deployment. . . . Much faster biofuel deployment is possible through new policies and addressing supply chain challenges. [14] Renewable heat accelerates amid high energy prices and policy momentum – but not enough to curb emissions. . . . [The renewable heat acceleration comes] predominantly from the growing reliance on electricity for process heat – notably with the adoption of heat pumps in non‑energy‑intensive industries – and the deployment of electric heat pumps and boilers in buildings, increasingly powered by renewable electricity."

"The world’s demand for electricity is rising at its fastest rate in years, driven by robust economic growth, intense heatwaves and increasing uptake of technologies that run on electricity such as EVs and heat pumps, according to a new report by the IEA. At the same time, renewables continue their rapid ascent, with solar PV on course to set new records. . . . Global electricity demand is forecast to grow by around 4% in 2024 and {will do so} into 2025, with growth around 4% again . . . . {The} share of global electricity supply {generated by renewables is} forecast to rise from 30% in 2023 to 35% in 2025. The amount of electricity generated by renewables worldwide in 2025 is forecast to eclipse the amount generated by coal for the first time. Solar PV alone is expected to meet roughly half of the growth in global electricity demand over 2024 and 2025 - with solar and wind combined meeting as much as three-quarters of the growth. Despite the sharp increases in renewables, global power generation from coal is unlikely to decline this year due to the strong growth in demand, especially in China and India . . . As a result, carbon dioxide (CO2) emissions from the global power sector are plateauing, with a slight increase in 2024 followed by a decline in 2025. …Some of the world’s major economies are registering particularly strong increases in electricity consumption. Demand in India is expected to surge by a massive 8% this year . . . . China is also set to see significant demand growth of more than 6% . . . . After declining in 2023 amid mild weather, electricity demand in the United States is forecast to rebound this year by 3% . . . . By contrast, the European Union will see . . . growth forecast at 1.7% . . . . In many parts of the world, increasing use of air-conditioning will remain a significant driver of electricity demand. Multiple regions faced intense heatwaves . . . . With the rise of artificial intelligence (AI), the electricity demand of data centres is drawing increased attention . . . ."

"Many people believe that humans can have a sustainable future by using solar panels and wind turbines. Unfortunately, the only truly sustainable course, in terms of moving in cycles with nature, is interacting with the environment in a manner similar to the approach used by chimpanzees and baboons. Even this approach will eventually lead to new and different species predominating. Over a long period, such as 10 million years, we can expect the vast majority of species currently alive will become extinct, regardless of how well these species fit in with nature’s plan. The key to the relative success of animals such as chimpanzees and baboons is living within a truly circular economy. Sunlight falling on trees provides the food they need. Waste products of their economy come back to the forest ecosystem as fertilizer. Pre-humans lost the circular economy when they learned to control fire over one million years ago, when they were still hunter-gatherers. With the controlled use of fire, cooked food became possible, making it easier to chew and digest food. The human body adapted to the use of cooked food by reducing the size of the jaw and digestive tract and increasing the size of the brain. This adaptation made pre-humans truly different from other animals. With the use of fire, pre-humans had many powers. They spent less time chewing, so they could spend more time making tools. They could burn down entire forests, if they so chose, to provide a better environment for the desired types of wild plants to grow. They could use the heat from fire to move to colder environments than the one to which they were originally adapted, thus allowing a greater total population. Once pre-humans could outcompete other species, the big problem became diminishing returns. For example, once the largest beasts were killed off, only smaller beasts were available to eat. The amount of effort required to kill these smaller beasts was not proportionately less, however."

"It’s difficult to convey the enormity of ecological overshoot in words. Words are simply inadequate to describe the wildlife holocaust; the damming, paving, plowing, logging, and excavation of the natural world; the billions of Hiroshima bombs worth of heat we’ve added to the world’s oceans by burning fossil fuels; the billions of tons of ice that has melted; the billions of tons of microplastics floating in the air, the water, the blood of every living being on Earth. Why is everyone not horrified every moment of every day by all of this? We are an adaptable species. We are comfortable. We are excellent at denial. We just want to get food on the table. So we exist with our blinders on, working hard not to see it so we can get through the day, once again. […] But we exist in a bubble that’s about to pop. We can’t do anything about it as individuals; all we can do is prepare ourselves mentally, physically, emotionally, and spiritually, and work to protect every single square inch of land and water for those beings who might outlast us so there will be something rather than nothing after we’re gone. We can’t prepare for what we don’t see coming. So let’s take our blinders off for just a few minutes, and see. We’ll put those blinders back on, so we can get through the day, but perhaps by seeing, we’ll work harder to protect what we love."

"… almost no one will ever want to give up the comforts of modernity, even if they claim to. So all countries will continue with trying to grow their economies and, for countries with some semblance of free elections, no politician or party will run on a platform of contracting the economy or of aiming for a steady state economy, without the rest of the world also doing the same (and without a world government, that won’t happen). As the various planetary boundaries get left further and further behind, the rhetoric about wanting to do something will increase, but the actions, if any, will be meagre and wholly inadequate for the task of getting us back to near some of those boundaries. Add to that, resources becoming harder to extract and collapse of civilisation is inevitable, at some point in the future… this [is] because humans act like any other species. There is no such thing as free will and so rational actions are not possible. We’ll just have to get used to business as usual playing out. A few environmentalists see the polycrisis for what it is but most seem to concentrate on climate change, so think that all we have to do is stop using fossil fuels… [and] that isn’t possible but, even if it is, those people’s primary objective is to preserve civilisation, a profoundly unsustainable enterprise. It would be satisfying to see the transition clearly fail (because it’s unsustainable in itself and can’t make an unsustainable civilisation sustainable) but only from an academic stand-point. Satisfying but also disappointing because, if the rest of our predicaments haven’t yet reached their outcomes, a true transition might keep the climate moderately liveable, for many or most, for a few decades longer, provided the air conditioning doesn’t pack up."

"To nature, there is nothing special about life, and definitely nothing special about one particular life-form: humans. Everything is following natural physical laws. If there are observations that something isn’t following physical laws, then we haven’t yet understood the laws that it is most assuredly following. What does it mean for life to be simply following physical laws and processes? Well, that’s up to the individual. It certainly means we don’t have free will. It means that no human is better than any other human or better than any other life form, or even better than a rock. It means nothing to a rock. To humans, which may be the only life form with the physical abilities to wonder what this means, it means that there is no better way to live that the way we are living at any point. Unless, as individuals, we define what better actually means. If it means more money, then, for most humans, there are better ways to live. If it means less damage to the rest of nature, then there are definitely better ways to live. But it all depends on what each individual wants out of life… It can be humbling (though that depends on one’s brain chemistry) to understand that we are just physical things. However, it can also lead to a total acceptance of the collapse of civilisation, since it isn’t anything special. Civilisation will end. The Earth will end. The Solar System will end, as will our galaxy, the Milky Way, and countless other galaxies… [and] there is nothing spiritual about life, about humans. There is nothing special about humans, about this time. We are simply following a path laid out by physical laws, as is evolution… [and] that’s a shame. It would be great to think that my essence could go on for ever, and still able to think rational thoughts, just to see how all this develops."
