However, technological research and commercialization have lower the cost by ten times during the past ten years, so common households will afford it soon. Now, the technology of China's solar power water heater is leading the world with the cost of a gas geyser. Although it doesn't save energy, it's green with huge potential of saving energy. China has a wide market and strong production capacity, and therefore, popularity has no technical problems and prices are competitive. Meanwhile, wind energy use should be promoted in suitable areas because it's cheaper than solar power. Maybe, the government needs to support in systems and prices to benefit the households which choose green energy.

We can hardly see any blue sky on sunny days. It is questionable how efficient solar power can be under this kind of sky.

It is quite practical and saves lots of money in electricity bills. Actually, in the city, those living on the top floors of high-rise buildings could use the same technology. However, property management companies do not allow you to install them, which puts off such energy-saving ideas. I wonder if the government could intervene in such a situation?

Although I don't do reseach, however, if it is within my financial capability, I wish that I could do something to use solar power. If more people have had tried on that, the chances for the government to consider its application will be higher.
