Solar energy is touted by many as the main energy source of the future so let us look at the advantages and disadvantages of solar energy. Solar energy has much more advantages than disadvantages but certain solar energy disadvantages are still a major stumbling block on the road towards the broader use of solar energy. Still, I will start this article in positive note by first discussing the advantages of solar energy.
As many of you already know solar energy is renewable energy source. Our sun is virtually an unlimited source of energy, and solar energy cannot be depleted unlike fossil fuels that will eventually become depleted. Once this happens world needs to have good alternatives and solar energy definitely look like one of the best possible alternatives.
Solar energy is environmentally friendly energy source that doesn't emit harmful carbon emissions that contribute to climate change like fossil fuels do. With every watt of energy generated from the Sun we need less fossil fuel, and with it we are actually reducing the impact of climate change. The latest studies have reported that an average home solar system is capable to eliminate 18 tons of greenhouse gas emissions from the environment each year. Solar energy also doesn't emit nitrogen oxide or sulphur dioxide meaning that it doesn't contribute to smog or acid rain.
Wind energy is touted as one of the most eco-friendly forms of renewable energy. Wind farms have been sprouting up in suitably windy places throughout the world. Accompanying new wind farms are complaints of health related problems.
Wind power may be the fastest developing renewable energy sector with the rather competitive prices but this doesn't mean that wind energy is a perfect energy source, as there are several things wind energy sector will need to improve in years to come.
First of all, wind energy sector despite being one of the most cost-competitive energy still cannot continue to maintain its current tremendous growth without the adequate incentives, as it is very clearly seen from the current situation in United States. This means that wind turbines will not only have to become cheaper but also more effective, and this can only be achieved with the help of science. This means that the technological development is one of the key components that will determine the future of wind power industry.
Wind and solar based energy systems need a support source of energy, either through a correlation to the power association, a backup generator, batteries, or fuel cells. Fuel-cell power generation is a different rising technology; it is based on the conversion of hydrogen energy into electric energy through an electro chemical process, which produces DC electricity, heat, and water.
Futurists envisage power stations where wind or solar energy are used to generate electric energy, which is then used to electrolyze water and produce hydrogen that could be stored and used by fuel cells to generate electric energy when needed, eliminating the need for additional endorsement sources. Renewable energy costs. Renewable energy is still more expensive option compared to oil and fossil fuels, and many people are still not ready to pay more for clean energy. Going green may look like a widely popular idea but for many people this idea is only popular if they are not required to pay more to go with it.
