In recent years the world has become aware of itself. That is to say the planet and the people on it. We knew burning fossil fuels, releasing CFC gases into the environment and general global warming was bad.
But we didn’t know to what extent. Now we do. Ireland is suffering from floods not seen in decades. Further afield the ice caps are melting, tsunamis and hurricanes are becoming commonplace and the earth seems to be fighting a losing battle with the sun’s U.V rays as our ozone layer is needled with polluted holes.
What can we do to stop the seemingly doomed outcome? That is what this article summary will tell you;
Wind and solar energy are examples of renewable energy sources. That means they can be used over and over again to power our machines and they will never run out. They are clean, infinite and most importantly free. No lives have to be torn asunder to harvest them (fighting over oil for example).
Solar energy can be used for heat, light and generating electricity. How is this done? Putting solar shingles on a rooftop or installing solar panels will absorb the energy.
Wind energy is harnessed, by means of wind turbines, along with the sun’s heat to help evaporate water in order for it to become rain. As it flows downhill its energy can be caught using hydroelectric power.
The organic matter in plants is called biomass, which can be used in bioenergy to create electricity and fuels.
Although hydrogen is plentiful on the earth it doesn’t exist as a gas on its own because it always combines itself with other atoms to form molecules, such as water (H20). If it’s contained on its own it can used for fuel or converted to electricity.
Heat can also be found in geothermal energy, which is the earth’s own internal heat. It can be used for electricity and heating and cooling systems.
The ocean is pulled by the moon and the sun. This is tidal energy. By harvesting this energy it can be used to create electricity. Others ways its energy can be used for this is the wind’s influence on it and the sun’s. The surface is heated more than its depths, by the sun, which presents another energy source.
The most noticeable feature of all these innovative methods of eco-friendly energy production is that they all seem to offer a solution and choice to electricity production. And how could the rest of our modern technology exist if not without electricity? Our computers, televisions, lights, phones, defibrillator’s, almost everything we use to aid us in this world are powered by electricity.
That should be reason enough to want to have the most environmentally friendly one available. We’re spoiled for choice!
