Currently it is MUCH cheaper and far more reliable. Wind power must maintain fossil fuel systems burning, on standby, while they generate their power. Currently wind costs around $0.09 a Kw h to produce while fossil fuels can be as low as $0.025 a KW h. Great strides are being made to increase the output of wind systems and allow them to operate over a wider range of wind speeds. This will bring the cost per watt generation down to competitive levels even without subsidies.
They have been the most efficient energy source available
Expensive to build, cheaper to run than using fossil fuels once it is built.
More expensive to instal, cheaper to run
No. Alternative energy means energy sources other than fossil fuels.
it is way better than fossil fuels
wind is a renewable energy source ,while fossil fuels are nonrenewable .
solor energy
Nuclear fuel has a higher energy density than fossil fuels.
What energy comes from things besides fossil fuels
In general, yes, but only because structures are in place to make fossil fuel more easily available and attainable. Most biofuels actually have the potential to be far cheaper, and they also help reduce dependence on foreign fossil fuels.
extracting energy from nuclear fuels is more expensive than extracting energy from fossil fuels
Fossil fuels (coal, oil and natural gas) are cheaper than renewable fuels because there is not yet any price on carbon dioxide emissions.
