Alternative Energy Source - Solar Energy

The sun is a totally renewable and easily obtainable energy source. The government encourages people to install solar panels on their houses and also subsidize people for that. My parents had installed the panels on the house about 10 years ago and we could use hot water anytime as we wish. It’s all free without using any gas or electricity. The only cost was for the initial installation. My friend owns a beauty salon in Taoyuan and she had installed the panels on the top of the building. She said these solar panels can help her to save lots of money on the hot water. She spent about 2 years to recover the cost that she invested in the panels. Now she didn’t need to count the cost of gas or electricity and she can make more money. Although the scientists don’t find the technology to lower the cost of solar panels yet, I still believe solar energy is the best alternative energy source in the world. Solar power energy will be more widely used in the near future.
