Fossil fuel is non-renewable energy, that means it will run out a day in future no matter how much it is under our earth’s crust. But nowadays we still heavily rely on fossil fuel as our major energy source. We use fossil fuel ( petrol, natural gas, coal ) to generate energy, for transportation and making many daily-use product ( plastic bag, nylon, PVC and etc. ). Can you imagine what will happen when the fossil fuel is exhausted?
Making a hydropower plant also means creating a dam. And dams are almost always made on rivers. Rivers are redirected and blocked. The negative thing about this is that it could cause disorder on the natural habitat, or environmental damages by changing the environment of the river both downstream and upstream. Population near that river is always relocated and also, there is this risk of a weak dam failing, causing major catastrophe when the huge bulk of water floods everything on its path.
Your electricity produces a “carbon footprint” depending on the mix of fuels used for power generation. Your home carbon footprint depends on how many kilowatt-hours (kWhs) of that electricity you use at home.
If we are to look at the world’s consumption on oil based products you can clearly see that it rises each day. One clear example for this is the traffic we see on our roads. And the production and reserves for this does not really grow in an instant. If we really have to seek a power source it should be the one that comes from a natural flowing stream of energy. And there’s nothing more available energy in the world than green energy.
We are going to have to be sensible, hardheaded and pragmatic about the whole thing. There are a lot of technologies we can pursue. And we must focus on the most efficient and the most cost effective. We can scrutinize solar, wind, geothermal, not to mention advanced biofuels. And that’s just the short list.
Tom wanted at least a half dozen hens. Their city ordinance allowed for this, but not for a rooster, which was okay with Tom and Barbara, because they weren’t planning to breed more chickens. A half dozen hens would give them just over two dozen eggs a week. Their manure, when added to their compost heap, will give them a superior fertilizer for their garden.
California’s Global Warming Solutions Act sets a rather lofty target of the state getting a third of its energy from renewables by 2020. The law has spurred growth in renewable power production and facilities construction. However, if the trend of corporate green power purchases continues, that goal may indeed be reachable.
