Residential and Non-Residential Buildings End-Use Energy Efficiency
Image of a large commercial building Buildings end-use efficiency RD&D decreases energy costs and improves the quality of buildings through the development of new or improved energy-related technologies, design strategies, energy management tools, construction practices, and building performance evaluation methods. Energy efficiency research:

  • Facilitates the construction and operation of buildings that are energy efficient, healthy and comfortable
  • Improves building affordability and value through the development of cost-effective, energy efficient building products and strategies
  • Reduces energy costs through the development and use of energy efficient consumer options for reducing or managing loads




Energy Innovations Small Grant
Photograph EISG provides funding to establish the feasibility of innovative energy research concepts. This program is intended to offer a simplified evaluation and funding process for small businesses, small non-profits, research institutions and individuals.




Energy-Related Environmental Research
Photograph Environmental RD&D provides public benefits by improving scientific understanding and/or addressing the environmental effects and costs of energy production, delivery and use in California. Environmental research:

  • Develops new electricity applications and products to solve environmental issues
  • Defines electricity systems facilities environmental impacts and mitigation
  • Determines how electricity generation contributes to global climate change and develops innovative mitigation approaches




Energy Systems Integration
Photograph Formerly called Strategic Energy Research, ESI RD&D activities cover two or more program areas, represent potential high-risk/high-reward advances or provide energy-related public interest science and/or technologies not addressed in other program areas. Activities include system-related projects that integrate renewable energy, advanced generation, energy efficiency and/or environmental technologies. Energy Systems Integration research:

  • Improves the reliability and efficiency of the electrical transmission, distribution and delivery grid
  • Makes the electricity system safer and more resistant to damage and interruptions from natural disasters
  • Identifies new electrical generation and transmission system management techniques




Environmentally-Preferred Advanced Generation (EPAG)
Photograph Advanced generation RD&D produces technologies that improve the efficiency, reliability and/or environmental performance of electric generation technologies and provides new, smaller, cost-effective technologies for distributed generation. RD&D in this sector reduces electricity production costs, fuel consumption and the environmental impacts of electricity production and distribution. Advanced generation technologies:
  • Comply with future environmental constraints without compromising system efficiency
  • Demonstrate innovative generation cycles by testing hybrid combinations of cycles, developing novel cycles and evaluating the potential for using mixed fuels or co-firing



Industrial/Agricultural/Water End-Use Energy Efficiency
Photograph Developing and demonstrating new technologies in this sector increases energy efficiency and reduces emissions and manufacturing costs for California industries, agriculture, and municipal water and wastewater systems. These new technologies improve the competitiveness of California businesses by:
  • Reducing the electricity used to transport and treat water and wastewater
  • Lowering the energy cost of industrial waste disposal and water decontamination
  • Improving on-site power quality and load management to improve electrical system reliability and capacity utilization
  • Enhancing process energy efficiency while reducing emissions and manufacturing costs



Renewable Energy Technologies
Photograph Renewable energy technologies RD&D provides California with more diversified energy sources, a more secure electricity infrastructure and improves the quality of the environment. These energy technologies include traditional renewable energy applications and renewable applications combined with fossil fuel-fired energy. Renewable energy research:
  • Lowers renewable energy capital and operating costs and improves conversion efficiency
  • Improves renewable energy reliability and power quality
  • Develops environmentally sound ways to use waste as an energy feedstock





Transportation Research
Photograph Transportation RD&D provides a sustainable foundation for California's future by building a cleaner and more diverse transportation system, which increases California's independence from foreign oil, improves the quality of its environment and increases the health benefits from a cleaner environment and higher air quality.Transportation research:
  • Accelerates the development, availability, and use of: alternative fuels, advanced vehicle technologies, and advanced transportation systems and strategies.
  • Cost-effectively reduces on-road and off-road petroleum use in the short- and long-term.
  • Advances science to inform transportation policy and planning decisions that benefit California's electricity and natural gas ratepayers.
