Green Energy Advantages And Disadvantages

According to the definition of green energy from Mother Nature Network, “Green energy comes from natural sources such as sunlight, wind, rain, tides, plants, algae and geothermal heat. These energy resources are renewable, meaning they 're naturally replenished. ” However, “fossil fuels are a finite resource that take millions of years to develop and will continue to diminish with use”. Comparing these two definitions of green energy and fossil fuel, it clearly displays that green energy has greater advantages than traditional fuels.

In recent years, more and more people explore the issue of global warming, but the most important causes of these problems are because of human pollution of the environment. There are many origins of pollution,

Scientists are trying to find a new ways to solve our electricity problem and recently they already made great progress on this field. They discovered solar radiation has a high amount of energy that can be converted to electricity. Now days, scientists are making effort on solving the problem which reduce the energy loss during the conversion between solar radiation and electricity. However, solar energy still has several obvious advantages.

First of all, solar energy is an abundant resource. Jane Hoffman said, “We know the sun as simply our nearest star, and that without it life on our planet would cease to exist.” Thus, we can comprehend that the sun gives us a lot of resources and this energy is stable and reliable for human beings. In adequate areas (for example: sunny space, marine, coastal, open rock ground), a steady stream of solar energy is available. The use of the process will not cause environmental pollution, and it does not produce greenhouse gases that make global warming

For example, in 1974, United States government built the Natural Energy Laboratory of Hawaii Authority (NELHA) at Keahole Point on the Kona coast of Hawaii, which use for generator electricity through the temperature changing of ocean. Hawaii has the best location for building the OTEC device, due to its warm surface water, access to very deep seabed, extremely cold water, and high electricity costs. The laboratory has become the leadership on researching on OTEC technology (Electric Power Monthly,
