Many countries use many fuels like fossil fuels, coal, oil or natural gas, but in some other countries they consume some alternative sources of energy like solar and wind energy. And I think this tendency has a beneficial effect on many countries because it can be good for the economy in many countries, but it can be not effective in many countries.
One primary reason why alternative energy is used in many countries is their price. Building air turbines is cheaper than building a factory. If we compare the price of turbines and factories and how much energy they produce we will see that they make the same amount of energy that can be used. As a result we can use cheap and eco-friendly energy which will not cause any pollution and damage to the environment.
On the other hand alternative energy like solar or wind are not universal for every type of area. For example solar energy is less effective in cold and areas where the sunlight is limited, or wind energy less effective in areas without wind. As a result in some areas like deserts without wind you can not use wind turbines, or in cold areas it is not effective. Consequently solar or wind energy can not be enough to any countries and they must use energy like coal,oil or natural gas.
In conclusion, alternative energy can be good for many countries because they have a positive effect on the economy and environment. But some countries can not use solar or wind energy because they do not have a good area and must use normal or not eco-friendly energy.
