Nowadays, a variety of energy has become less and less, such as oil, gas and coal, etc. So it is time for us to choose a renewable and economical energy to sustain our consumption. As for me, solar energy should be the first choice and no other power can compete for it.
First all of, solar energy is low in cost and save money in the long run. After the initial installation of the appliance, the energy from the sun is practically free. What's more, the problems of energy shortages are becoming more and more serious, solar energy will become more price-competitive. In the long run, it will be cheaper than any kind of energy. After the initial investment has been recovered, everything after that is profit. It will save you money on electricity bill and gas bill in the next 15 or 20 years, or even longer time.

Secondly, solar energy is clean, renewable and environmentally friendly. We never have to worry about running out of solar power or using it up. According to a survey, the solar energy received by our planet only covers one-two billionth of all energy giving off by the sun surface, which is equivalent to 3-4 million times of the total energy needed for the global, so we can say it is inexhaustible in supply and always available for use. It is also sustainable and can be used every day only there's sunlight. Besides, it does not pollute air by releasing carbon dioxide, nitrogen oxide or mercury into the atmosphere like many traditional forms of electrical generations does. It actively contributes to the decrease of harmful green house gas emissions.
Thirdly, it is safe and convenient to obtain. There is no need to worry about gas poisoning or electric leakage when using solar power. What you need to pay attention to is careful for the hot water, and do not burn yourself. Besides, you can obtain hot water in any time after installing solar appliance, especially in some regions where there is a high number of sunshine hours. And in some poor areas, people have to use kerosene and candles for domestic heating and lighting, solar energy is available for their heating and electricity. For some households with excess energy, solar energy can be stored for night-time use, which can reduce their energy fee.
Above all, solar energy is a best choice for your household use, no matter from what aspects, it is economical.renewable and sustainable. And people can benefit from it in the long run, especially in saving large amount of energy.
