A gift from a star

In the book Our Choice comes a quote from Albert Einstein that got my attention. “I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until coil and oil run out before we tackle that.” The sun is a star which provides great amounts of heat to our planet Earth and is necessary for the living organisms’ life. With the intelligence of humans, they have noticed that the heat can be transformed to use it as energy, and then electricity. This would reduce the amount of CO2 released to the atmosphere and that could be a way to solve global warming.
With the quote I realized that people have had this idea of using the sun since a very long time ago, but still, a small amount of people use this alternative. Why are we not using it, if it is “free” as a gift?

I think that it is because this source of energy is very expensive: the equipment and installation, but after this is all the energy received from the sun is free. You don’t have to pay for it, and it can be used for a long period of time. So it will be a benefit to the owners. I think that if all the people or at least some countries start implementing this, the price will lower, and more people will be able to obtain it (price-demand). And less pollution will be produced.
Also I think that another way of taking advantage of the sun is that the houses should have the ceilings of window. As in the United States, some of the buildings have plants in the highest floor so they can receive solar energy. With this type of ceiling not only plants can be in there, but also people could use that solar energy instead of light bulbs. Or maybe it can also be stored and used.

We must be responsible for our home. The sun will always be there while we are living, so why don’t we are a little selfish and start using it for our and Earth’s benefit? Let’s start using it!!
