There are many serious efforts being made to discover alternative sources of power that will make a difference in this world. On top of corruption and poverty, the mess our world is in is aggravated greatly by pollution. A number of groups – and corporate firms – are worried about this and are taking action to effect a reduction of greenhouse gases and other pollutants. Reducing toxins has been a reason for seeking inexhaustible energy sources, and this is a by-product of the use of energy. Renewable energy can impact people’s lives profoundly, yet the great majority are generally ignorant of it. The following is a list of the most popular sources of energy and some basic understanding.
Perhaps the best known alternative is solar, which collect energy from the sun’s rays in solar cells. The rays of the sun are stored in thermal panels which transform the heat to electrical energy. In addition, steam can be produced by the rays hitting parabolic mirrors, causing the water to get hot. You don’t have to rely totally on science, though, since a lot of light and heat can be channeled into your home just by drawing the curtains or opening the blinds. Of course, one issue is that the sun’s energy can’t be collected with ease when it’s foggy or dark. Because of the cost involved, there are few huge solar power stations.
One thing you observe a great deal more of these days is the growing use of wind power. Try to drive down many highways, and you will see numerous wind turbines with their big blades. The wind turns the blades which drive an electric generator, creating electrical energy. These days, there are large-scale wind farms, generating electrical currents, that are distributed to electrical grids across the country. A number of houses and businesses have their own small wind turbines to bring in electric power. Aside from the fact that it doesn’t create detrimental byproducts, is that you can rely on the wind to blow.
Another renewable energy, which originates from below the earth’s surface, is geothermal energy. Turbines are powered by steam released through drilling into hot rocks deep under the surface of the earth. This creates electrical power without any damage to the environment if done correctly. An expensive setup cost is the drawback to these very efficient geothermal energy plants. Falling water, which powers turbines to generate electrical power, has been used for quite a while now at dams. One other way to take advantage of the kinetic power of water is provided by its tidal flow.
Reading about the many alternative energy sources shows the grandeur of nature’s myriad workings. We have to become more aware and play a larger role in taking care of our earth, and learning about renewable sources of energy is one way to start.
