Today, we are now aware of the effects of global warming. Fortunately, it’s not too late and we can still change which is why many are pushing for green energy technology sources. The advantage of using green energy sources is that it is clean so it does not emit anything harmful into the air which has an impact on the environment. It is also renewable which means we will never run out of it unlike oil which is expected to dry up in a decade or so. Although green energy technology facilities are expensive to build, it requires less maintenance so you don’t have to shell out a lot of money to operate it. It can also bring economic benefits to certain areas even boost tourism. While these sound good, there are some who say that there are disadvantages to using such green energy technology. While green energy sources can produce electricity, how much it can generate is not consistent. This is because we have no control of the weather so if a certain area relies on solar energy and there is a weather disturbance, it will not be able to convert sunlight into electricity. Building these facilities also requires a lot of land so we may have to cut on farmland which is what many are concerned about if more wind turbines are to be put up. Another disadvantage is the fact that some of the green energy sources cannot be installed in certain areas of the planet. For instance, wave energy can only be utilized if the waves coming from the ocean reach at least 16 feet. The use geothermal energy can only be done in geologically unstable parts of the planet. But if you look at such arguments, places that cannot use one form of green energy technology can be substituted for another. If wind turbines need more space, they can be installed near the coast instead of putting these on land. A study shows that you can generate more electricity while these are placed out in the ocean water. While the weather is something we cannot control, it is not everyday that there is a weather...
