Now he gets to see how it works nearly every day, after his school got a new energy system for producing solar power. 　　The solar energy system provides the whole school with power, including its computers, kitchens, science labs and so on. Before the school could use the solar energy system, Mathew said it had serious power problems, especially in summer. A huge amount of power was needed in summer. The school was very worried about it. “But today the situation has much improved，” he said. “Solar energy is so good that it supports the whole school.” 　　The purpose of the project is to bring cheap, clean and steady(稳定的) energy to the classrooms by changing traditional power supply(供应) into solar power. Besides protecting the environment and providing steady energy supply, changing traditional power supply into solar power has also cut the school's energy bills. 　　The teacher who controlled the solar energy system said the students had got a new understanding of green energy. “Our students now see and understand the influence of solar power，” he said. “They learn the importance of clean energy and how it keeps our environment clean.”The system is spreading knowledge not only among students, but also in their homes and the neighbouring villages.
