Renewable Energies

Sunlight, wind, wave power, this are some of the “nature powers”. Renewable energies are those that take advantage of these powers to produce that energy that we use in ours days to cook, to have light at night and so on.
Solar panels are the ones used to store the sun energy and to convert it into electric energy to be used at home. This energy is also use to warm up water that it’s going through a tube and receiving that energy it gets warmer.
The wind, a powerful energy, is usually stored with those windmills that we see on the hills and, basically, they are everywhere but there should be a lot more out there to produce even more energy.
Waves, sometimes we’re at the beach and, out of nowhere, a strong wave appears and put all of our things wet or even drag us down. This power is also exploited by putting a mechanism under the water but that we can see it at surface, not at the beaches because they are usually a bit far from the coast.
