Fossil fuels are limited in quantity, and we are already running out of them, so we need to replace them with something else.
Also, burning fossil fuels in the large quantities we do changes the balance of nature. We are experiencing global warming, but also there have long been pollution problems with fossil fuels.
Fortunately, there are already alternatives. There are many of these, but one example might suffice to provide an example.
Fire wood can be gasified. The tars that are created, which often go into the atmosphere when wood is burned, can be trapped quite easily, and have commercial value or can be burned to fuel continued wood gasification. The wood gas produced can be catalyzed into alkanes, a class of chemicals that includes propane, butane, and octane. You can get just about any alkane you want, so you can decided to produce diesel oil, if that is what you want, and what you get is superior in nearly all respects to what is pumped from the ground. Five kilos of wood produces one liter of diesel oil - that is about 120 gallons from a cord of wood. If this is done using sustainable forestry techniques, the effect on the forest is probably beneficial, and the carbon footprint is quite possibly about a third of that of nuclear power.
A problem that we have with energy is that we are limited to very few sources for economic reasons. The model of centralized power generation and fuel production is easy to fund because it makes sense for big businesses to invest in. The tendency is for the few centralized sources to crowd out a larger number of smaller, distributed sources. But the distributed alternative can derive power from a larger variety of sources, producing a smaller environmental impact with each, and using less in the way of non-renewable resources.
On a personal level: If your home is warmed sorely by electric central heating and the electricity is suddenly cut off (winter storm bringing down power-lines, for instance), to also having a gas supply is beneficial. The gas oven in the kitchen could be lit and left on a low gas mark with the door open to help keep the house reasonably warm - or frost-free. You could still cook on the gas stove. You could even have your own electricity generator in the garage that you can supply the house until the mains came back on.

Renewable energy sources are important because they are clean. They release no carbon dioxide, so they have no effect on global warming. Our continued reliance on fossil fuels for energy is harming the environment.
No. Alternative energy means energy sources other than fossil fuels.
Fossil fuels.
Not all energy sources come from fossil fluels. Fossil fuel energy sources are coal, crude oil. None fossil fuels energy sources are wind power, solar power, tidal power. It is arguable for atomic power , using uranium .
solor energy
natural gas
Fossil fuel is not energy its a energy source and yes there is more energy sources besides the fossil fuel like coal and others.
since fossil fuels can be found almost anywhere in the world we need to improve sources of energy so that they are around the world............
nonrenewable energy sources are sources that are depleted sources as fossil fuels (wood, coal, natural gas, and oil)
solar energy and energy from fossil fuels
Because by using alternative energy sources, we cut down on the use of fossil fuels, which are bad for the environment and will run out with overuse.
They are called renewables. (though strictly, nuclear power is not a fossil fuel and is not renewable).They are called alternative energy sources.
