This report by Ember reviews 25 years of offshore wind development in Britain, tracing its growth from the first 'truly offshore' wind farm at Blyth in 2000 to a sector that now provides 17% of the country's total electricity generation. It highlights the industry's role in re-industrialisation, the success of the 'Contracts for Difference' policy, and the challenges posed by supply chain constraints and inflation.

This report by Ember outlines policy recommendations to unlock the potential of hybrid power plants in Türkiye, suggesting that straightforward regulatory changes could realize at least 8 GW of potential capacity.

This report by Global Energy Monitor analyzes the growth potential of geothermal power in the United States under the Trump administration. It highlights how bipartisan support, technological advancements in Enhanced Geothermal Systems (EGS), and streamlined permitting are positioning geothermal energy for rapid expansion, particularly to meet the 24/7 power demands of AI data centers, even as other renewables like wind and solar face political headwinds.

This case study examines the 'Varanasi model' for scaling rooftop solar (RTS) in India under the PM Surya Ghar Muft Bijli Yojana. By coordinating state, district, and city administrations with utilities and banks, Varanasi significantly increased RTS installations between February and December 2024, providing a blueprint for other Indian districts to achieve renewable energy targets.

A fact sheet by Ember and Initiative Klimaneutrales Deutschland analyzing the untapped wind energy potential in Bavaria, Germany, and the impact of distance regulations on the region's energy transition and gas dependency.

The report analyzes the growth of solar and wind energy in the ASEAN region, highlighting that while there has been significant expansion—largely driven by Viet Nam—stronger policy support and grid modernization are required to meet the IEA's 2050 net zero scenario. To align with this scenario, the region must reach a 23% share of solar and wind in total electricity generation by 2030, necessitating the addition of 164 GW of solar and 65 GW of wind capacity.

This report by Energy Innovation argues that while the economics of clean energy are now competitive with fossil fuels, non-financial risks—specifically project development and market uncertainty—are hindering deployment in the United States. The authors propose 'investment-grade policies' to reduce these risks, focusing on transmission access, streamlined siting and permitting, and long-term cost-recovery schedules to lower the cost of capital for developers.

This research paper analyzes the determinants of distributed solar photovoltaic (PV) generation penetration across 5,563 municipalities in Brazil. The study finds that demand-side factors—specifically population, GDP, and electricity tariffs—are more significant predictors of PV adoption than the availability of solar resources. The authors argue that current tariff subsidies in high-potential regions like the Northeast may be hindering PV growth and suggest that climate mitigation policies must address demand-side frictions to be effective.

This case study by the Climate Policy Initiative examines the trajectory of Spain's concentrated solar power (CSP) industry, detailing how initial successful incentives led to rapid deployment and innovation, followed by a collapse in investor confidence due to retroactive policy changes and a lack of cost-control mechanisms.

This executive summary analyzes the impact of capacity factor (FC) estimation manipulation within Brazil's Programa de Incentivo a Fontes Alternativas (PROINFA), a feed-in tariff (FiT) scheme. The authors find that project developers systematically inflated FC estimates to secure higher payments and larger contracted energy volumes, leading to financial overpayments and lower-than-planned energy generation. The report suggests that a simple 1% interest penalty on excess payments would have eliminated these incentives for manipulation.

This executive summary analyzes the Incentive Program to Alternative Sources (PROINFA), a feed-in tariff (FiT) implemented in Brazil in the early 2000s. While the program successfully increased installed wind capacity from 29 MW in 2004 to 2,010 MW in 2012, the authors find that flaws in contract design led to systematic misreporting of capacity factors (CF) by project developers. This misreporting resulted in overpayments and a shortfall in delivered energy, suggesting that simple design changes, such as interest rate penalties on overpayments, could improve the cost-effectiveness of similar renewable energy policies.

This working paper by the World Resources Institute examines the initial impact of the Karnataka Electricity Regulatory Commission's (KERC) August 2014 order (S/03/01), which exempted solar power generators achieving Commercial Operation Date before 31 March 2018 from wheeling, banking, and cross subsidy charges for ten years. While the order is welcomed by market participants, the paper finds that tangible on-ground impacts in terms of commissioned megawatts or wheeled energy units will likely only be visible from the fourth quarter of Financial Year 2016 onwards due to the time required for project planning, land acquisition, and power evacuation.

This report by the World Resources Institute examines Concentrating Solar Thermal power (CST) as a large-scale, zero-carbon alternative to coal-fired power generation. It highlights the role of thermal storage in providing baseload power and discusses the policy and economic barriers—such as high upfront capital costs and the need for carbon pricing—that must be addressed to accelerate global deployment, particularly in rapidly developing economies.
