Why is it so hard to use the green or renewable energy?

Renewable energy is everywhere around us
and we know that. Why don’t we use it more often? The answer is simple. We don’t
know how to use it in an efficient way. When we are at home, we need a
continuous source of energy, without any interruptions. Wind, sun, biomass and
other renewable sources are unpredictable and hard to control. Therefore, we
rather use fossil fuels, such as coal, oil and natural gas. This might be a
temporary solution, but what will happen when the fossil fuels run out. It is
true that it will not happen in our lifetime, but what about the future
generations. They will need to figure it out how to use the renewable energy.

 Green energy needs large investments and
that is one of main reasons why people do not use it. We could expect that in
the future the prices of renewable energy will be much lower because there will
be many technological developments in the future.

 In order to increase the outputs of green
power generators, it is important to optimize them. We can optimize them by
using advanced software, sensors and measuring devices. For example, wind power
can be optimized by anemometers.
