2025 has already ushered in a mixture of regulatory shifts, technological advancements, and both public and private sector leadership. The Environmental Protection Agency (EPA) is reconsidering previously adopted federal vehicle emission standards that would effectively require an increased share of electric vehicles (EVs) in the market. While proponents of the regulations view them as a necessary step toward meeting climate goals, critics argue that the required rapid transition may impose technological and economic challenges, particularly for heavy-duty transportation and long-haul trucking.
One of the most debated regulatory changes so far this year is EPA’s decision to revisit Greenhouse Gas (GHG) …
View Full ResourceNatural disasters (NDs) including earthquakes, floods, tsunamis, and other high-impact natural phenomena cause significant power outages that interrupt human activity and industrial output. Natural disaster mitigation in the energy sector requires sophisticated control strategies, operations, and vulnerabilities. In literature, different Microgrids (MGs) configurations are adapted in such scenarios which can endure low-probability and high-impact (LPHI) occurrences because of their compact size, manageable loads, and constrained bounds. Ad hoc MGs that are low-power, transportable, and containerized can be used in emergencies by supplying electricity for critical loads. This paper includes an overview of the history of power system resilience, resilience-enhancing techniques, …
View Full ResourceInclusive utility investment is a financial solution for distributed clean energy upgrades – including DERs and energy efficiency – via a tariff for site-specific utility investment and cost recovery, approved by the utility’s regulatory authority and designed to ensure net annual cost savings for participants. SEPA partnered with Clean Energy Works to raise awareness of the value and use cases of inclusive utility investment programs, such as Pay As You Save® (PAYS®). These programs can provide financial benefits to utilities, utility customers, and building owners. Inclusive Utility Investment Guide for Distributed Energy Resources – developed with extensive contributions from industry …
View Full ResourceDollar incentives for energy upgrades have enormous potential for impact. They can spur transformation by lowering up-front costs and making upgrades more accessible and appealing for households. And they can help drive wary contractors to recommend and install more energy efficient equipment such as heat pumps.
However, incentive uptake is not happening at the pace and scale needed to tackle the millions of poorly sealed and insulated homes that waste energy, raise costs, and rely on inefficient fossil fuel equipment. Incentive programs are needlessly complex, bogged down by excessive reporting, and burdened by ever-changing rules. Consumers can’t make sense of …
View Full ResourceHydrogen is a strategic economic and energy opportunity to expand America’s industrial base, energy security, and global leadership. Despite good progress made in the past several years, the US hydrogen industry faces headwinds and slow scale up. The more its market lags, the more it risks falling behind other countries actively building markets and securing supply chains.
This report explores the conditions stalling US hydrogen market growth, including weak domestic demand caused by fragmented policies and challenged economics in many domestic offtake sectors. With case studies for hydrogen in exports, on-road mobility, aviation, steel, and maritime shipping, it highlights the …
View Full ResourceHeatwaves challenge electricity systems relying on wind energy for renewable power. However, the global availability of wind power during heatwaves remains unknown. Here, the authors provide a global assessment of wind power dynamics during heatwaves using weather reanalysis data from 1980 to 2023. The results show the global land area experiencing wind power shortages during heatwaves has risen by 6.3% per decade, reaching 60% by 2023. Australia, Northern Asia, and Europe are particularly vulnerable, with wind power decreasing by 30–50%. Conversely, regions such as the Amazon, the Great Plains in North America, and Central Africa experience slight increases in wind …
View Full ResourceThe relevance of the study is due to the need to increase the energy autonomy of livestock farms by introducing innovative solutions based on computational intelligence. Given the significant energy consumption by livestock farms, as well as the reduced dependence on traditional energy sources, there is a need to optimise energy systems using renewable sources. The aim of the research is to develop a model for integrating computational intelligence to optimise energy systems of livestock farms to achieve their energy autonomy. The use of computational models will allow farmers to manage energy consumption more efficiently, minimise carbon emissions, and increase …
View Full ResourceRenewable power generation capacity is measured as the maximum net generating capacity of power plants and other installations that use renewable energy sources to produce electricity. For most countries and technologies, the data reflects the capacity installed and connected at the end of the calendar year. Data has been obtained from various sources, including an IRENA questionnaire, official national statistics, industry association reports, other reports, and news articles.
At the end of 2024, global renewable power capacity amounted to 4 448 GW. Solar, in line with the previous year, accounted for the largest share of the global total, with a …

View Full ResourceAnthropogenic emission reductions resulting from carbon neutrality and clean air policies in China, one of the world’s major emitters of carbon dioxide (CO2) and aerosols, are likely to influence regional and global photovoltaic (PV) outputs by affecting climate change. Here, the authors use the Community Earth System Model version 2 (CESM2) to assess quantitatively how China’s emission reductions toward carbon neutrality will influence the PV potential (PVPOT) and the extremely low PV outputs in the mid-21st century (2041−2060). They find that the large reductions in anthropogenic emissions in the context of China’s carbon neutrality will increase the PVPOT and reduce …
