Disadvantages of Renewable energy sources

Disadvantages of Renewable energy sources

A common disadvantage to all is that it is difficult to produce the large quantities of electricity their counterpart the fossil fuels are able to. Since they are also new technologies, the cost of initiating them is high.

Wind: Turbines are expensive. Wind doesn't blow all the time, so they have to be part of a larger plan.

Solar: Panels are expensive. Governments are not all willing to buy home generated electricity. Not all climates are suitable for solar panels.

Waves: Different technologies are being tried around the world Scientists 

Tides: Barrages (dams) across river mouths are expensive to build and disrupt shipping. Smaller turbines are cheaper and easier to install.

Rivers: Dams are expensive to build and disrupt the environment. They have also caused earthquakes.

Geothermal: Difficult to drill two or three kilometers down into the earth.

Biofuel: Oȅen uses crop lands and crops (like corn) to produce the bio-alcohol.
