Energy Efficiency

Our Clean Technology clients have developed energy-efficient technologies for buildings, homes, transportation and power systems that reduce energy consumption, help to control global emissions of greenhouse gases, and otherwise reduce carbon footprints. The federal Office of Energy Efficiency and Renewable Energy (EERE) seeks to "strengthen America's energy security, environmental quality, and economic vitality in public-private partnerships that: enhance energy efficiency and productivity, bring clean, reliable and affordable energy technologies to the marketplace; and make a difference in the everyday lives of Americans." Perkins Coie attorneys share this goal and support our clients in the developing, selling or buying of energy-conserving and energy-efficient products and technologies. As we are fluent with government policies in energy efficiency, such as California's 2020 and 2030 zero net energy initiatives, we are able to provide detailed and forward-thinking counsel to clients to help strengthen and protect their companies and technologies. Our attorneys are experienced with working on matters involving carbon markets and carbon regulation, green building, energy-efficient transportation technologies and clean air and water technologies.

Renewables/Alternative Energy

Our Clean Technology clients develop technological advancements that use alternative energy to replace traditional fossil fuels, including wind power and wind generation, solar power and solar energy, hydropower, geothermal energy, biomass conversion, biothermal energy, recovered energy and clean conventional energy generation. We work with local, state and federal regulatory agencies to ensure these technologies are environmentally sound and help our clients obtain federal and state grants, cooperative agreements and loan guarantees for renewable energy projects. We secure siting and permitting for Clean Technology energy facilities and work with publicly traded, investor-owned and independent renewable energy power producers generating and trading renewable energy, carbon offsets and renewable energy credits from biomass conversion, biofuels, geothermal, hydropower, recovered energy, solar power, water power and wind.

Perkins Coie attorneys have a long-standing commitment to meeting today's needs without compromising future generations. We are proud to continue this commitment by representing and counseling Clean Technology industry leaders and innovators. All the resources and experience of our firm are at the disposal of our clients, and we know how to bring those resources to bear in a practical and efficient manner to achieve solutions.
