Renewable Energy: The Future of Our Planet?
Is renewable energy the future of our planet? This is a question many people find themselves asking as more and more of us being "going green" in an effort to do what we can for the environment. Renewable energies are becoming more and more popular, in no small part because they are renewing and, perhaps more importantly, because they are self renewing. The fact of the matter is that many of the energies we have relied upon for the past century are in danger of running out. Even those which are still rich pose a problem, as we finally begin asking ourselves how we are tasking the Earth itself by stealing some of its most valuable resources. As people search for the answers to such questions, they often become bogged down and confused by scientific jargon. Hopefully the following article will clear up things considerably.
Before understanding renewable energy itself, you have to understand what most countries now use for energy: natural gas, oil, and coal. And as we are all pretty well aware, these substances cause quite a lot of controversies these days. They are considered fossil fuels, and fossil fuels cannot renew themselves. They are finite. Once they run out, they are gone.
Renewable energy is, of course, the exact opposite. The wind produces renewable energy, as does the sun. Ideally, neither the wind nor the sun will ever run out. Most often, renewable energy is created by the sun. some of that energy is directly solar powered and some of it is indirectly solar powered. Solar power can be used for a wide variety of power resources. For example, you can use it to both heat and cool your home, you can use it to light your home, it can provide your electricity, heat your water, and much, much more. Naturally, it will do the same for any other building or abode as well.
These are not the only types of renewable energy, however. There is geothermal energy as well, which uses the internal heat of the Earth itself for a variety of things. For instance, it can produce electric power, it can both heat and cool any type of buildings, and many other things as well.
Are these renewable energy resources the keys to the future of our planet? Many, many people would say yes, and with good reason. We are all aware of the many oil crises we have gone through, we know about gas shortages, we are seeing things change. The weather has gone as crazy as a patient in a lunatic asylum, with summer temperatures cresting one hundred one day and dropping down thirty degrees or more the next day. Cold rains come in July but do very little to cool down the temperatures. We see pollution, and the price of all of our emissions as well.
We need a new type of energy - or, better yet, a choice of energies, energies which are able to renew themselves and erase the worry of us ever running out of them.
