Fossil fuels (oil, gas, coil) are the main source of energy for many countries. However, alternative sources of energy (like solar, wind, etc.) have been encouraged by some countries. To what extent is this a positive or negative development?

Energy

provision has always been one of the main concerns of every nation. Recently, there have been some motivations for implementing clean

energy

in a number of countries,

instead

of fossil fuels.

This

trend is more of a positive one, and plenty of advantages can be mentioned

for

in

it.

First

of all, utilizing renewable sources of

energy

like solar, wind, waves, etc., can reduce, if not eliminate, the drawbacks of using fossil fuels. To illustrate,

great

greater

amounts of pollutants are being emitted to the atmosphere as a consequence of burning oil and gas.

However

, the alternative sources of

energy

are environmentally-friendly, and produce no emissions. Another important advantage of renewable energies is that they are not limited. According to some experts, the fossil fuels will be depleted in the near future, and they should be replaced by other resources as soon as possible. So, finding a new technology becomes of great importance. Apart from being limitless, as well as causing no damage to the environment, renewable sources of

energy

are not restricted to particular areas, and almost everywhere across the world benefits from at least one type of these sources. Almost everywhere receives plenty of sunshine every day. In some places, like Sweden, other sources,

such

as wind, can compensate for the inadequate radiation.

Nevertheless

, these sources still have not been developed technologically. The systems implementing renewable

energy

, are not generating power with the desired efficiency. As an example, the efficiency of a solar panel is roughly 20 percent, while the internal combustion engines that burn gas, are producing power with an average efficiency of 90 percent.

However

, considering the fact that fossil fuel power generation units have been developed hundreds of years ago, undoubtedly,

the clean

cleaner

energy

systems will become highly efficient, as well. In conclusion, renewable

energy

systems are capable of benefiting the world by emitting no greenhouse gases, being accessible almost everywhere, and being limitless.

Although

they are not as efficient as the fossil fuel systems, their development by the passage of time is beyond dispute.
