Those who use solar energy help us save our precious fnel. As you know, our supplies of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs. And when Mother Nature says that’s all, that’s all. The only way we can delay hearing those words is by starting to save energy now and by using other sources, such as the sun.
We won’t have to worry about the sun’s running out of energy for another several billion years or so. Beside being an endless source of energy, the use of the sun has other advantages as well. The sun does not offer as many problems as other energy sources. For example, fossil fuel plants add to already high pollution levels. With solar energy, we will still need these sources of energy, but we won’t need as much. That means that we can cut down our pollution problems.
Furthermore, owners of solar homes will have extra protection against rising fuel costs. They will also have some protection against fuel shortages. When utility(公用事业的) costs go up, as they surely will, owners of solar homes won’t have to face the burdens brought about by increased costs.
With all these good points, why don’t we see more of solar power? There are many reasons for this. The biggest reason is money. Until now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy around. All that has changed now. Solar costs are starting to equal the costs of oil and electricity. And experts say that gas will triple in cost in the next few years. In fact, gas is in such short supply right now that, in some places, it is not sold to new customers. Some customers are even having their supplies cut back.
Solar energy is now in its infancy. It could soon grow to become a major part of our nation’s energy supply.
The biggest reason for not using more solar power now is ______.
