We live in a world where the need for energy is continually growing. But how will we be able to meet the ever-growing demands, if we primarily depend on non-renewable resources? Today, fossil fuels supply more than 85% of the world's energy. Sooner or later we will have to look for alternatives. It's always better sooner than later.
Why alternatives? Two reasons - energy supply and environmental concerns. We all know fossil fuels will eventually run out. By some estimates, they may be depleted within the next 50 years or so. Fossil fuels were formed from organic materials (dead plants and animals) over hundreds of millions of years and cannot be renewed. When they run out, they are gone for good.
The second reason is pollution. We use fossil fuels by burning (combustion) which produces many pollutants - carbon dioxide, sulfur dioxide, nitrogen oxides, and volatile organic compounds. Emissions from the consumption of oil, natural gas, and coal, are responsible for approximately 80% of yearly carbon dioxide emissions in the world. This affects both our health and the environment.
The future is definitely in renewable energy sources like solar power and wind power. They come in practically unlimited supplies and don't pollute the environment like fossil fuels do.
By increasing the use of alternative energy sources, we could slowly start decreasing our dependence on fossil fuels. The best thing about renewable sources is that they will never run out.
One of the biggest reasons why renewable energy is not used more often is the cost. But this is positively changing. The technology is improving and the costs for solar, wind, and other renewable sources are going down.
There is no doubt, renewable energy sources are the future and it is up to us to smooth the transition from fossil fuels. The sooner we start, the better.
