The Clean Energy States Alliance (CESA) prepared this case study to describe how New York’s state energy office, the New York State Energy Research and Development Authority (NYSERDA), collaborated with community-based organizations (CBOs) while administering the state’s PON 3414 Affordable Solar and Storage Predevelopment and Technical Assistance Program. This program has benefitted many low-and-moderate income (LMI) residents in New York by providing equitable access to solar energy and/or energy storage. The program is flexible to the needs of CBOs representing LMI communities, ensures the benefits of the solar and/or storage projects flow to LMI residents, and provides funding for the …
View Full ResourceSince federal clean energy incentives were passed last year, signs of rapid growth for maturing American clean energy industries are emerging. U.S. wind manufacturing plants that closed in recent years are bringing back workers. Plans for an unprecedented amount of new solar, battery, and offshore wind plants are being drawn and developed. The U.S. is in a position to secure our energy independence and become a global leader in the buildout of clean energy.
The new incentives offer companies significant opportunity to invest in new utility-scale wind, solar, and storage projects and manufacturing facilities, while passing on savings to American …
View Full ResourceA thorough predevelopment process for a potential solar or solar+storage project is essential to deciding whether the project can and should move forward. Predevelopment includes site identification, financial modeling, estimating equipment and installer expenses, customer outreach and enrollment, and other details about the scope of the project. This process can be expensive, and many for-profit solar developers only invest money into predevelopment when they already believe a project is likely to be able to move forward. Financing for predevelopment costs is usually not available to community-based organizations working to develop solar or solar+storage to benefit low-and-moderate income (LMI) residents because …
View Full ResourceAs more renewable energy sources are used, power systems must become more flexible and adjustable to balance supply with demand. To achieve this, services are required that span from fractions of a second to seasonal time scales. Solar and wind power will become increasingly critical, but their intermittent nature will result in nearly twice the annual variability in residual demand compared to today. EVs have the potential to provide grid-connected storage and in doing so revolutionise the way we use and manage energy.
In this white paper we examine the concepts of vehicle-to-grid (V2G) and vehicle-to-everything (V2X) technology, the landscape …
View Full ResourceThe International Renewable Energy Agency (IRENA) produces comprehensive, reliable datasets on renewable energy capacity and use worldwide. Renewable energy statistics 2023 provides datasets on power-generation capacity for 2013-2022, actual power generation for 2013-2021 and renewable energy balances for over 150 countries and areas for 2020-2021.
Data was obtained from a variety of sources, including an IRENA questionnaire, official national statistics, industry association reports, consultant reports and news articles. Major trends in the sector worldwide are outlined in the accompanying brief, Renewable energy highlights.
The yearbook also includes statistics on investments in renewables, compiled from the OECD-DAC database and 20 major …
View Full ResourceThis paper explores the interplay between projected renewable energy additions onto the electricity grid in Texas operated by the Electric Reliability Council of Texas (ERCOT) and the region’s existing electrical transmission network.
Without expanding ERCOT’s electrical transmission network and storage capacity, congestion and curtailments will rise. Curtailments are due to both inadequate transmission capacity and surplus generation during high availability periods of variable renewable generation.
Transmission system upgrades could reduce some curtailments that arise from transmission capacity limitations. But curtailments resulting from surplus generation cannot be mitigated by transmission system upgrades and storage. With the addition of variable renewable generating …
View Full ResourceIn this report, ACP finds that Colorado is making significant strides in the clean energy sector, with wind and solar providing over one-third of the state’s electricity. The state’s clean energy capacity, currently at approximately 7,000 MW, is set to grow significantly by 2030. Current capacity is enough to power 2.5 million homes. And the sector – which currently employs more than 15,000 Coloradans – is poised for further expansion.
Clean energy in the state has grown by way of nearly $14 billion of capital investment into not only utility-scale solar, storage, and wind projects, but also into a robust …
View Full ResourceIn April 2019, WPTO launched the HydroWIRES Initiative to understand, enable, and improve hydropower and pumped storage hydropower’s (PSH’s) contributions to reliability, resilience, and integration in the rapidly evolving U.S. electricity system. The unique characteristics of hydropower, including PSH, make it well suited to provide a range of storage, generation flexibility, and other grid services to support the cost-effective integration of variable renewable resources. The U.S. electricity system is rapidly evolving, bringing both opportunities and challenges for the hydropower sector. While increasing deployment of variable renewables such as wind and solar have enabled low-cost, clean energy in many U.S. regions, …
View Full ResourceThe urgent need to develop alternatives to fossil gas is underscored on a near-daily basis. To achieve ambitious decarbonization goals set forth by countries, states, municipalities and corporations, alternative fuels need to scale quickly. This report from Ameresco explores emerging alternatives to fossil gas including green hydrogen and biomethane, the latter of which is also known as renewable natural gas (RNG). RNG has the capacity to scale quickly, and it also has the potential to augment and support the development of green hydrogen.

Direct air carbon capture and storage (DACCS) involves a set of approaches for capturing CO2 directly from the air and its subsequent long-term storage. DACCS is at an early stage of technical development and currently faces a variety of challenges, including high cost and energy requirements. Building on publicly available data, this paper provides: (i) an overview and classification of DACCS systems, (ii) a harmonization of technical and economic performance of direct air capture technologies, (iii) a comprehensive list of technical- and infrastructure-based obstacles to scaling DACCS systems, and (iv) a roadmap and list of priority initiatives for research, development, …
