Solar Energy and Wind Energy

Introduction

The earth's resources are normally divided into nonrenewable and renewable resources. Some renewable resources are everlasting, meaning that they are not affected by a human being use, such as wind energy or solar energy. Other renewable resources are inorganic and organic materials that replenished by biochemical and physical cycles. The main sources of renewable energy are biomass (wood and waste burn for fuel), hydroelectric power (energy produced from flowing water), geothermal sources (energy from heat sources in the earth's surface), Tidal energy (gravitational forces of attraction between the Moon, Earth and Sun resulting from the tides), solar (energy from the sun), and wind energy. Nonrenewable resources are those materials that are present in the earth in limited amounts (minerals) or produced only over many millions of years (fossil fuels). Nonrenewable resources may be recyclable so that their usefulness to human beings can be extended, but often they transformed during use into useless matter such as waste gas. The term renewable energy covers a range of energy sources in theory, which depleted over time. These sources would be an alternative to other conventional sources (non-renewable) and produce a minimal environmental impact. Renewable resources are those that can be reused or recycled in some way. For example, the trees are used to make furniture, and then reused to make other things, and nonrenewable used only once, and cannot be used again. For example, water. The difference is that renewable used more than once nonrenewable can only be used a single time. The focus would be on the development of renewable energies, particularly wind and solar (thermal and photovoltaic).

Discussion

Solar Energy

Solar energy is light from the sun, in the form of radiant light and heat that can be harnessed directly or indirectly by a variety of technologies. This form of energy is being increasingly utilized in an attempt to meet society's need for power generation, and discussion of the feasibility of large-scale solar power production is likely to occupy a prominent position in the news media and public discussion for some time, as supplies of fossil fuels such as coal and oil diminish and global climate change (related to fossil fuel consumption) becomes a more apparent reality (Bradford, 2006). It is essential to note, however, that even without the use of technologies such as solar photovoltaic cells that “actively” exploit solar energy, solar energy affects us every day through the power it imparts to our weather systems, its heating of our atmosphere, and its acting as a source of energy for the natural world. Through the process of photosynthesis, plants capture vast amounts of solar energy annually. Directly or indirectly the majority of renewable resources come from the sun. The amount of solar energy reaching the earth is 28,000 times greater than conventional amount of primary energy consumed.
