What’s the problem? Unfortunately, many people think that our planet have an unlimited sources of energy. They are wrong! We can accumulate energy, but it’s not enough. So lets discuss the ways of saving energy on the Earth.
The Solution First of all, we should use renewable sources of energy. For example – solar battery. It’s rather cheap and useful. As I remember the Sun will disappear after few billions years. So, it’s almost endless source. Solar batteries are also used in many European countries.
Other ways In some northern countries these batteries are not useful cause of a little amount of sun during the year. So what should we do? Another way to solve this problem are wind generators. In Russia we can get more than 10% of energy from wind.
If we haven’t an opportunity to use other sources… Economize, economize and economize again. Our planet is a miracle! It can gives us everything we need. But sometimes we use more than we need. We waste energy! It’s awful. But the worst thing – is that we haven’t notice it. It’s so easy to turn off the light or water when we don’t use them.
Have a look We take energy for our own. And that’s why nature suffers from lack of it.
