In a time when the major nations of the world are looking to find more sustainable energy sources, renewable energy must play a key part of any long term strategy. Renewable energy comes from natural sources such as the sun, wind power, wave energy, geothermal, biomass and hydroelectric power.
These alternative energy sources are much more sustainable, as the power sources will not run out. It is also much more environmentally friendly as they do not involve a burning process. These factors are the complete opposite to non-renewable energy sources such as oil, coal and natural gas.
The focus is shifting toward sustainable energy sources, due to the world depletion of fossil fuels. The gap between the availability and demand of such energy is significantly increasing, therefore value and cost of these energy sources is rising. The most widely used renewable power source is solar power, Latin for ’sun’, a powerful source of energy. There are two forms to contain the energy – thermal and photovoltaic. Thermal power converts sunlight into heat, applying it to a steam generator in order to warm buildings, heat water and generate electricity. Photovoltaic power uses solar cells or panels, when sunlight strikes the semiconductor material and creates an electric current. Other solar technologies concentrated power plants, solar towers and portable solar.
Collection of solar energy can be undertaken anywhere in the world; however, localities on or near the equator can leverage more due to proximity and daylight hours. Solar energy have preferable qualities compared to use of fossil fuels, for example is that it will be constantly available throughout time, environmentally friendly and relatively easy to maintain. Problematic issues include factors solar energy is restrictive for locations near the poles of the earth, cloud cover can reduce efficiency and PV cells are relatively expensive.
Renewable power can support small and large scale applications and operations. Applications include use of renewable energy to produce electricity, heat, steam, lighting, cooling, water heating, and mechanical energy. These sustainable energy sources are important to industrial and domestic users. Businesses and industry use these technologies to diversify their energy sources, improve efficiency and cut overhead costs.
Over the last few decades, it is clear that increasing energy demands, environmental problems and depletion of fossil fuels have made us look at different, more sustainable energy options. Alternative energy sources are being increasingly used by providers of utilities and property developers, to provide more sustainable energy for villages, small towns and cities.
Different types of renewable power technologies are used in different parts of the world, depending on climatic conditions. It is seen that the United States have more solar power plants, Europe has more wind power plants and China has the most hydroelectric power plants.
