Fossil fuels are predominant in today's energy system and account for more than 85% of the world's energy consumption. Today, the need for energy is enormous, plus it's constantly growing and will continue to do so. How can we meet the energy demands, if we predominantly depend on fossil fuels? We can't, and sooner or later we will have to find alternatives.
There are two main reasons - energy supply problems and environmental problems. As we know, fossil fuels are in limited supply. They are non-renewable and will eventually be depleted. They were formed millions of years ago from dead plants and animals and cannot be replenished. When they run out, they run out. By some estimates, they will be depleted by 2050.
Another growing concern is environmental pollution. Today, the combustion of fossil fuels is one of the biggest source of atmospheric pollution. Burning fossil fuels produces carbon dioxide, sulfur dioxide, nitrogen oxides, and many other poisonous chemicals that go into the air, water, and ground. This causes both health and environmental issues such as smog, acid rain, climate change, ozone depletion, and so on.
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.
Our overly dependence on fossil fuels is not a good thing and we should start making serious efforts to decrease it. Being dependant on something that will soon run out, is not very healthy.
The main objection against green energy is the cost. That's true, renewable energy is generally more expensive, but for how long? When fossil fuels start to run out, the price will climb and we won't have a viable replacement.
Green and renewable energy should be our main focus in the coming decades. The sooner we become free of our fossil fuel addiction, the better.
