问题描述:

If the Earth's atmosphere absorbs o million times human's energy requirements from the sun, why is there an energy crisis?

解析:

There is an energy crisis because we cannot use the sun's energy efficiently, the solar panel is the method that we use to absorb sun's energy, howeverm this technology is expensive and also takes a lot of space. Furthermore, it is subject to weather conditions, those problems dont exist for other energy sources such as oil, oil can produce energy regardless of weather and its cheaper as pares to the solar panel. however, as the technology improves, the solar panel will be more widely available and hence the sun;s energy can be more efficiently used. the scientists around the world have all started working on the improvement of the efficiency of the solar panels.
