hydro energy.Nuclear energy, solar energy, wind energy tide and thermal energy are a few that come to mind.
Because there is no suitable alternative at present
No. Alternative energy means energy sources other than fossil fuels.
Because to date there is no viable alternative to fossil fuels, that are plentiful and cost effective.
Fossil fuels are exhaustible. Electric energy is an alternative.
Fossil fuels and uranium
Alternatives fuels are fuels that are not made from fossil fuels (coal, oil and natural gas).
Fossil fuels come from fossilied plant matter in the ground. Alternative fuels are alternatives to fossil fuels, and these are mainly carbon fuels that take their carbon from carbon dioxide in the atmosphere (as fossil fuels do) but on a carbon cycle with a much shorter term. An example is wood, which can be burned as more trees are growing and absorbing carbon dioxide.
Alternative fuels are renewable and produce fewer greenhouse gas emissions compared to fossil fuels, such as gasoline and coal, which are non-renewable and contribute significantly to air pollution and climate change. Examples of alternative fuels include biofuels, hydrogen, and electricity. Overall, alternative fuels are considered more sustainable and environmentally friendly than fossil fuels.
Even the harshest global warming critic can't give you the answer you are looking for. There is nothing redeeming about fossil fuels. The only reason that fossil fuels are used is because we have yet to discover and implement on a wide scale a cheaper and cleaner alternative.
Fossil fuels-including coal, natural gas, and oil-are formed from the fossilized remains of prehistoric plants and animals, and fossil fuels provide about 95% of the world's total energy. Alternative fuels are better for the environment and often better for the economy than fossil fuels. Learn about the controversies and conservation plans surrounding fossil fuels, and explore the alternatives.
Hydroelectric power is an alternative to production of electricity produced by fossil fuels
Solar energy is a potential alternative for fossil fuels. It is a renewable source of energy and will be available as long as the sun lasts.
