Sustainable energy sources wind power

A major problem with the new sustainable energy sources is their reliability. Inherently they will produce electricity as the wind blows and the sun shines. The need for power is not constant either, with peak demands during the day. Hence, ways are needed to store energy that enable release on demand. Synthetic fuels and methanol are candidates, but the most important will be hydrogen. It can be produced conveniently from water and electricity with a reasonably high efficiency of 70 %. Hydrogen is the ideal fuel for fuel cells. 

Other concerns regarding energy use and preservation should be considered. It is necessary to develop policies that allow organic farms to convert to sustainable energy sources, such as wind power or solar power, through special tax breaks or low-interest loans. 

The diversification of energy sources tailored to the requirements and resources of each country using nature s renewable resources such as the sun (photovoltaics), wind power, geothermal energy and biomass is a definite requirement. If solar cells are chosen to provide an alternative to fossil fuels, significant research work is needed (i) to develop new routes for the production of crystalline silicon, (ii) in the development of amorphous silicon hybrid materials that could result in enhanced efficiencies, (iii) for further development of thin-layer technology, (iv) in concerted efforts for cheaper and more stable dyes, (v) in improving the efficiency of the dye-sensitized cells and (vi) in process development to deliver enhanced device performances, ensure sustainability and reduce production costs on an industrial scale. 

Sustainable Energy Technologies (SET) was contracted to develop an interface converter with the capability to accept a power input from a photovoltaic or wind source. SET delivered two 5 kW photovoltaic interface converters that were tested by Northern Power Systems in Waitsfield, Vermont... 

The transition towards a world economy based on energy supply via sustainable sources such as wind-, hydro- and solar energy, or nuclear power (of which fission still suffers from a bad public image caused by concerns over nuclear waste and proliferation, whereas fusion has so far failed to live up to its potential) is therefore expected to be a lengthy process that cannot be expected to be solely responsible for the stabilization of atmospheric greenhouse gas concentrations in this century. Rather, a combination of many of the mitigation alternatives will need to be adopted to significantly curb CO2 emissions. 

If wind energy is combined with another sustainable energy supply, e.g. solar power, these combined sources of power would be ideal for developed and developing countries to provide a steady, reliable supply of electricity. 

Demand for sustainable energy generation leading to an increased amount of variable sources of power generation with low predictability like wind energy... 

Offshore wind power has recently become a highly sought after source of sustainable energy. It consists of the generation of electricity through wind turbine farms located in bodies of water off the coast. Wind farms are increasingly proposed offshore as there are higher wind speeds available and they do not take up valuable land space.
