Solar panels

Once you believe about it, solar panels are ingenious little devices. They take light and they turn it into electrical energy. Who would ever have thought a hundred years ago that it would have been feasible to complete that? How numerous of us even now are capable to explain it? We might understand that yes, you will find solar cells on the roof. When the light hits them, they produce electrical energy. It sounds simple enough and but it isn't all that long ago that folks would have considered it an impossible magic act. You put an object within the light and from that fact electrical energy is produced. It doesn't actually sound possible, except it does now simply because we are all so employed to it.

The implications of this, when taken to their conclusion, are that we have a potentially free form of energy. It's renewable energy so that is basically what that means. Potentially then we can power the whole world without creating any pollution within the mean time. Nothing ought to be able to get in our way of doing that except that it does. Let's say that by burning oil for one minute we can produce 100 units of energy. How numerous units of energy would a solar panel produce? Properly, at the moment it would be nowhere near 100, it probably wouldn't even be 50. It would possibly be closer to 20. That means that if we replaced all of the energy we get from oil with solar energy, we would probably need to be generating it for at least five occasions as long. We would not be able to wait that long though so we would require 5 times as a lot.

Obviously we can't ignore the economic implications either. This would make producing energy at least five occasions a lot more costly, and each business would have to cope with that. Would they all survive? Definitely not, and that means that there would have to be an economic contraction. The size of the economic system truly describes how many individuals it could assistance so if it went on for long enough then it would mean the population would have to contract by that a lot too.

So at the moment photovoltaic cells are nowhere near the renewable energy source we need them to be to be able to stave off the effects of oil on the atmosphere. We just have to keep going or else accept that lots of people are not going to survive.
