When solar energy is available in abundance why we rely on oil and other alternative?
Why can solar energy be not used everywhere? Is it very expensive to tap it?
Solar energy is (or was) very expensive, yes. That is changing. current costs versus long term power production are falling, however. At present, the cost is borderline.
However, solar energy alone is not a complete answer. First of all, for the production of electricity, it has some problems. The main one, of course, is tha tit doesn't work at night. You either need a storage system (batteries) or an alternative source when it's dark or cloudy.
There are alternatives which, combined with solar energy, can replace coal. Wind, existing hydroelectric systems, nuclear energy, and tidal power are some of them.
Myy point is, don't fall into thhe trap of fixating on a single all-encompassing cure-all technology. We need a mix of technologies. That's true today--we use coal, oil, nuclear, hydroelectric, and other sources--a mix of technologies to provide our energy needs. We need to change themix--eliminating fossil fuels and incorporating new technologies to replace those fossil fuels. There is no simple solution.
Now-as to oil--it is used primarily for transportation. In some ways it is ideal: its easy to store and the fuel stores the energy, whichis released when it's burned.
There are alternatives. The one I think the most practical is to use electric cars. Current technology makes electric cars with performance and adequate range possible at prices comparable to gas-powered cars (once they are produced in large numbers as gas-powered cars are). That's acutally a solved problem. What we do not have is a way of producing the electricity to power all those cars (without buring oil or coal, which defeats the purpose) at present. For that--go back to the first part of this post.
But we also do not have a practical infrastructure to deliver that electricity to a fleet of 150 millioncars (in the US). That is not a trivial problem. Think of what it takes to deliver a gallon of gas from an oil well to your car. Here's the sequence. Oil well to pipeline (hundreds of miles) to refinery to another pipeline to atanker truck to an gas storage tank under a gas station and then a pump to take the gas out o fthe tank and deliver it to your car.
And remember, you need tha tinfrastructure so comprehensive that it blankets an entire CONTINENT.
You will need the samme for electric cars (or any other alternative).
I don't mean to discourage you--this is doable. We DID do jsut that in the early 20th century to make our current system of gs-driven cars possible. But that took decades--and a hellava lot of engineering and research.
But--as to your question--we wil get solar power on a large scale in the foreseeable future. But we will need a lot more. It's a complex problem--and a big one.
