As the supply of fossil fuels decreases, it is increasingly possible for us to adopt a series of new technologies to help us obtain more and more energy directly from the sun. First, we will capture and guide solar radiation to illuminate and heat buildings; bully, we will use photovoltaic cells to convert solar energy into electricity; again, concentrated solar power stations will direct sunlight to the receiver to use steam Turbines or heat engines generate electricity; finally, we can even build solar-powered satellites in space to transmit energy to the earth.

      The most effective way to use solar energy is to use its light and heat directly. To a certain extent, it can be achieved passively by installing large double-layer or triple-E glass windows in well-insulated buildings. In order to maximize the use of passive solar energy, homes and workplaces usually require thicker walls and floors, which will maintain and slowly release heat. The more positive aspect is that more and more solar lighting and heating technologies have been invented one after another and are likely to become popular.
