Describe three alternative energy technologies, and identify two ways that hydrogen could be used as a fuel source in the future. Answer in a few sentences.
1. Solar energy: Solar panels capture sunlight and convert it into electricity, providing a sustainable and renewable source of power. This technology can be used in both small-scale residential systems and large-scale utility projects.
2. Wind energy: Wind turbines harness the power of wind to generate electricity, offering another clean and renewable energy option. Wind farms can be constructed on land or offshore to take advantage of strong and consistent winds.
3. Geothermal energy: Geothermal power plants utilize heat from the earth's core to produce electricity. This form of energy is reliable and constant, as it does not rely on weather conditions like solar or wind power.
In the future, hydrogen could be used as a fuel source in the following ways:
1. As a fuel for transportation: Hydrogen fuel cells can power vehicles, enabling zero-emission transportation. This technology could reduce greenhouse gas emissions and dependence on fossil fuels in the transportation sector.
2. Energy storage: Hydrogen can also be used as a means of storing excess energy generated from renewable sources. By converting electricity into hydrogen through electrolysis, the gas can be stored and later converted back into electricity when needed, providing a valuable energy storage solution for balancing the grid.
