If you look at the disadvantages of renewable energy, they are quite less than the advantages; nevertheless, here are the disadvantages. One of the best sources of renewable energy is solar energy. There is no question of solar energy ever running out like non-renewable sources like natural fuels.
One day the natural fuels of the world are going to finish, maybe a couple of centuries from now, maybe earlier, but they will not be renewed again. But the Sun, the wind, the Tides and the waves as well as geothermal energy are always going to be there. Therefore, is the biomass energy going to be there forever.
However, they have their own disadvantages. Solar energy is the most important source of energy to us. In fact, fossil fuels would not have been there if there were not for the process of photosynthesis, which made those plants stay alive, all those millenniums ago.
The advantage of solar energy is that it can be collected with the help of solar panels. The disadvantage is that how are you would collect all this energy if you are living in the Polar region, where the sun does not not appear for six months of the year. And if you're living in a place which is perpetually covered with clouds, sorry, it is going to be very difficult to collect solar energy. Unless a cheaper substitute for photovoltaic cells is found, they are going to be expensive means of collecting solar energy.
Geothermal energy harnesses the energy, which is collected below the surface of the earth. Hot water from this area is pumped up so that buildings can be heated. The disadvantage of this system is that geothermal energy can be harnessed only in places where they are volcanoes and the hot rocks, which produce heat, are easily accessible under the surface. The water pumped up, may sometimes contain dangerous trace elements like sulphur.
Harnessing the energy of the wind might be sensible, but to harness that energy, you have to link together a number of turbines that are extremely noisy.
