Biofuels, Solar and Wind as Renewable Energy Systems: Benefits and Risks. With shortages of fossil energy and heavy biomass energy use occurring in both developed and developing countries, a major focus has developed worldwide on renewable energy systems. Currently, a heavy focus is on biofuels made from crops, crop residues and wood. Though it may seem beneficial to use renewable plant materials for biofuel, their use raises many concerns about major environmental problems, including food shortages and serious destruction of vital soil resources. All renewable energy systems need to be investigated because humankind has limited oil, gas and coal reserves remaining. In addition, coal will become increasingly difficult to extract and....

Easily available energy has sup-ported major advances in agriculture, industry, transportation, and indeed many diverse activities valued by humans. Now world petroleum and natural gas sup-plies have peaked and their supplies will slowly decline over the next 40–50 years until depleted. Although small amounts of petroleum and natural gas will remain underground, it will be energetically and economically impossible to extract. In the United States, coal supplies could be available for as long as 40–50 years, depending on how rapidly coal is utilized as a replacement for petroleum and natural gas. Having been comfortable with the security provided by fossil energy, especially petroleum and natural gas, we appear to be slow to recognize the energy crisis in the U.S. and world. Serious energy conservation and research on viable renewable en-ergy technologies are needed. Several renewable energy technologies already exist, but sound research is needed to improve their effectiveness and economics. Most of the renewable energy technologies are influenced by geographic location and face problems of intermittent energy supply and storage. Most renewable technologies require extensive land; a few researchers have even suggested that one-half of all land biomass could be harvested in order to supply the U.S. with 30% of its liquid fuel! Some optimistic investigations of renewable energy have failed to recognize that only 0.1% of the solar energy is captured annually in the U.S. by all the green plants, including agriculture, forestry, and grasslands. Photovoltaics can collect about 200 times more solar energy per year than green plants. The green plants took more than 700 million years to collect and then be stored as the concentrated energy found in petroleum, natural gas, and coal supplies. This book examines various renewable energy technologies and reports on their potential to supply the United States and other nations with needed energy. Some chapters examine several renewable energy technologies and their potential to re-place fossil fuel, while others focus on one specific technology and its potential, as well as its limitations. In this volume, the aim of the contributors is to share their analyses as a basis for more research in renewable energy technologies. Basic to all the renewable energy technologies is that they attempt to minimize damage to the environment that supports all life. v ... - tailieumienphi.vn 667047
