With the invention of the automobile, man realized just how much he could do and where he could go just by putting gas in it and driving. And beyond our cars, by putting gasoline engines in other objects we shortened the time it took to cut our grass, trim our weeds and ready our gardens for planting. Then came natural gas, propane gas and fuel oil to heat our homes and now we no longer had to chop wood to stay warm. Coal created electricity and we no longer had to burn candles at night to see, we simply flip a switch. We never stopped to think at the time though, about what it was doing to our atmosphere, or how much we were starting to use and depend on fossil fuels.
Fossil fuels are a nonrenewable source of energy. Coal, oil and natural gas take millions of years to form. There are limited amounts of each of these in our earth, and once it is gone, it is gone. It will take many generations for any type of fossil fuel to return. At the rate we are using fossil fuels, we will probably run out of coal in around 250 years, natural gas in about 70 years, and oil in around 45-50 years. We use fossil fuels in almost every area of our lives. Not only do we use them, but farmers use them to plant and harvest their crops. They also use fossil fuels to transport livestock, vegetables and grain to warehouses to become the food on our table. Police, ambulances and firemen use fossil fuels to protect us and keep us safe. All around us every minute of every day fossil fuels are being used in some form. We have to find alternate forms of energy before it is too late and fossil fuels are gone.
Scientists have been studying renewable sources of energy for years now. While renewable sources of energy have been used in some places, daily renewable energy usage is small compared to the daily usage of non-renewable sources of energy. Some sources of renewable energy are solar power, water (hydro) power, wind power and geothermal power. These forms of renewable energy have been...
