 Petrolejový gigant  Chevron a obnovitelné energie
Renewable energy refers to energy resources that are not depleted as they are consumed or converted to other forms of energy. Renewables include solar energy used directly or converted to electricity; wind power; hydroelectric power; geothermal energy; ocean and tidal energy; biomass fuels; and – depending on how it's produced –; hydrogen. Renewables complement fossil fuels and other sources in meeting the world's energy requirements. In the year 2000, for example, coal fueled 39 percent of worldwide electricity generation, followed by renewables (mostly hydroelectric) at 19 percent, natural gas (17 percent), nuclear (17 percent), and oil (8 percent). (Source: International Energy Agency, Renewables for Power Generation 2003.) Environmental and energy security concerns and, in some situations, favorable economics, are promoting public interest, R&D, and investment in renewable energy. Although the amount of energy produced from renewables will increase in coming years, informed projections show that renewables will be just one part of the overall energy picture. Chevron's Approach Chevron works to provide reliable, affordable energy, produced in a safe and environmentally responsible manner. As part of our broader energy development strategy, we are actively engaged in developing cleaner, diversified energy resources that are commercially competitive. Our approach to pursuing potential energy sources is based on the fact that such investments compete in the marketplace against conventional energy sources and must be considered in context of the Company's broader energy development strategy. Chevron is actively pursuing selected renewable energy technologies as part of a larger effort that includes investing in alternative energy sources, energy efficiency, cleaner fuels, natural gas, gas-to-liquids, and other promising advanced energy sources and technology. The Company's objective is to maintain a balanced, economically sound energy portfolio while continually working to minimize the environmental impacts of energy development and use. Back to Top Chevron's Activities Between 1999 and 2003, ChevronTexaco invested approximately $110 million per year in renewable energy, alternative energy, and energy efficiency. We have two business units dedicated to developing and commercializing new and emerging energy sources: Chevron Technology Ventures (CTV) and Chevron Energy Solutions (CES). CTV's Hydrogen Business Unit develops and commercializes hydrogen technologies, while its Emerging Energy Group is responsible for coordinating the Company's efforts in renewable energy technologies. Chevron Energy Solutions delivers energy efficiency, conservation, energy management and power system solutions to public institutions and businesses, including hydrogen fuel cell and solar photovoltaic installations. Examples of Chevron's activities in renewable, alternative and advanced energy include: Renewables Operates a 500 kW solar array at our Bakersfield, CA production location – one of the largest solar photovoltaic installations in the United States and the first such facility in California to power oil field operations Built and operates one of two geothermal power plants in Indonesia that together generate 145 Mw Engineered and installed a 191 kW solar electric system, a 360 kW cogeneration system, and a heat recovery system at the Pierce College campus of the Los Angeles County (California) Community College District Invested in a 22.5 Mw wind farm at the Nerefco refinery in the Netherlands Designed and operates a 200kW hydrogen fuel cell power plant at the corporation's data center in San Ramon, CA – the first commercial site in the San Francisco Bay Area with fuel cell power – and a similar unit at its Bellaire, Texas, offices. Installed high-efficiency lighting and control systems in conjunction with a solar photovoltaic system to reduce energy consumption by 20 percent at Moscone Convention Center in San Francisco, California. Hydrogen Fuel processing for fuel cells. Working from its expertise in fossil fuels and in the near-term commercialization of new energy sources, Chevron is pursuing conversion technologies to produce hydrogen for fuel cells systems. These are based on traditional fuels such as natural gas for transportation and distributed power generation applications. Advanced batteries. Our 50-50 joint venture, COBASYS LLC, is working to commercialize nickel-metal hydride batteries for such applications as hybrid electric vehicles and for stationary power devices. U.S. Department of Energy Programs. Chevron actively participates in U.S. Department of Energy (DOE) hydrogen programs, including: U.S. FreedomCAR initiative Cost-shared R&D in hydrogen fuel generation In addition, Chevron is the only U.S. energy company leading a team in competition for a multi-year DOE award to demonstrate hydrogen vehicles and infrastructure installations. Looking to the Future Chevron believes renewable and alternative energy sources are important in the overall energy mix for the global economy. However, the widespread use of renewable energy sources depends on many factors, including technical progress, market acceptance, and economic viability. With 125 years of experience, Chevron will continue to meet energy demands as new markets, sources, and opportunities develop. ZDROJ:www.chevron.com
