  • 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.

  • Energy is important for the existence and development of humankind and is a key issue in international politics, the economy, military preparedness, and diplomacy. To reduce the impact of conventional energy sources on the environment, much attention should be paid to the development of new energy and renewable energy resources. Solar energy, which is environment friendly, is renewable and can serve as a sustainable energy source. Hence, it will certainly become an important part of the future energy structure with the increasingly drying up of the terrestrial fossil fuel.

  • Renewable Energy is energy generated from natural resources - such as sunlight, wind, rain, tides and geothermal heat - which are naturally replenished. In 2008, about 18% of global final energy consumption came from renewables, with 13% coming from traditional biomass, such as wood burning. Hydroelectricity was the next largest renewable source, providing 3% (15% of global electricity generation), followed by solar hot water/heating, which contributed with 1.3%. Modern technologies, such as geothermal energy, wind power, solar power, and ocean energy together provided some 0.

  • The present edition has been updated in a number of renewable energy technology areas (Chapter 4 and 5), where progress have been made over the recent years. New solar simulation studies have been added to Chapter 6, and market considerations have been included in the overview in Chapter 1, and in discussing industry liberalisation in Chapter 7. The remarks on advanced subjects made in the preface to the 2nd edition are still valid. A new growth area is fuel cells for stationary and mobile uses of hydrogen and other fuels.

  • Civilization is on a non-renewable energy course upon which we are dependent and which can only be maintained by increasing use of fossil fuel oil and gas and coal, with the result of rising greenhouse gas levels and increasing climate change that leads to increasing ecosystem destruction. It is imperative that civilization bring about an energy transition to a renewable energy economy, which may be based on inexhaustible solar energy, hydrogen, and electricity derived from renewable sources.

  • Renewable energy sources such as solar power, wind power, hydroelectric power, geothermal power, and so on have attracted much attention as alternatives to fossil fuels, because toxins and pollutants are not produced by these sources. For this reason, these energy sources have come to be known as clean energy.

  • A production tax credit (PTC) is an example of such a performance-based incentive that provides the investor or owner of an eligible renewable energy system with an annual tax credit based on the amount of electricity generated by the system. By linking the incentive to energy produced rather than capital invested, this type of incentive encourages and rewards projects based on performance.

  • Renewable energy is shifting from the fringe to the mainstream of sustainable development. Past donor efforts achieved modest results but often were not sustained or replicated, which leads now to greater market orientation. Markets for rural household lighting with solar home systems, biogas, and small hydro power have expanded through rural entrepreneurship, government programs, and donor assistance, serving millions of households. Applications in agriculture, small industry, and social services are emerging. Public programs resulted in 220 million improved biomass cook stoves.

  • Despite the many perks of renewable energy systems, there are several barriers to market development. The first and foremost of these barriers is cost. Most small-scale renewable energy technologies are substantially more expensive on a dollars-per-watt basis than conventional sources. Part of this cost inequity can be attributed to the array of generous subsidies for fossil and nuclear power. (These subsidies are so long-standing and well entrenched in the marketplace that they are hardly considered subsidies any longer.

  • There are also institutional issues to resolve. A path-dependent technology pattern has developed in the energy field that encourages the current centralized generation model of energy supply. When shifting away the capital investments in technology from centrally planned facilities toward distributed generation, renewable energy technologies and their prospective customers must fight against a tide of perceptions, practices, and market structures designed to facilitate the old central-station ways.
