Green energies have a lot of advantages. First of all, green energies such as wind or solar energy are way friendlier with the environment than other energy sources like the ones based on combustion. For example, if you have a fireplace you will probably need wood to make it work and in order to obtain wood a tree must be cut down. Second of all, green energies do not produce CO2 a highly contaminant gas because they are not related to any type of combustion process which are responsible of the CO2 production. Finally, this energies are renewable so it does not matter how much we use it, there is always going to be more.
Nevertheless, it also has some disadvantages. One argument against these new green technologies is that they are way more expensive than other methods to produce energy. For instance, to buy a solar panel capable of producing energy for a single room costs more than two hundred dollars. In addition, in case of solar and wind energy they need a lot of maintenance to produce electricity in an efficient way because in order to work they need to be placed in unprotected location which can end up in people stealing and breaking the energy devices and as we all know repairs are expensive. A third argument is that the efficiency depends on weather conditions. As a result, if there is not enough sun or wind the amount of produced energy will be significantly reduced.
To sum up, there are advantages and disadvantages when we talk about new methods to produce energy and it is our task now to decided what is more important between green energy which takes a lot of money and effort or a simpler but less eco-friendly method such as combustion energy.
