WIND ENERGY: It has a similar drawback to solar energy in that it is not constant. Although wind energy is sustainable and will never run out, the wind isn’t always blowing.
- This can cause serious problems for wind farm developers. One of the most common disadvantages of wind turbines is the noise pollution they generate.
The initial cost of purchasing a solar system is fairly high. Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops.
- Solar panels are dependent on sunlight to effectively gather solar energy. This energy has to be used right away, or it can be stored in large batteries.
TIDAL ENERGY: There are very few ideal locations for construction of plant and they too are localized to coastal regions only.
- It influences aquatic life adversely and can disrupt migration of fish. The actual generation is for a short period of time. The tides only happen twice a day so electricity can be produced only for that time.
- Frozen sea, low or weak tides, straight shorelines, low tidal rise or fall are some of the obstructions.
BIOGAS ENERGY: After refinement and compression, biogas still contains impurities.
While combustion of biogas, like natural gas, produces carbon dioxide (CO2), a greenhouse gas, the carbon in biogas comes from plant matter that fixed this carbon from atmospheric CO2.
