Fossil fuels are running out. What’s next? What would happen if we ran out of energy? Our whole way of life would be flipped upside down! But, that is what could happen if we keep relying on fossil fuels as our major energy resource. One way to solve this problem is to use photovoltaic energy. Unlike fossil fuels, photovoltaic energy doesn’t release harmful carbon dioxide into the earth’s atmosphere, which would help reduce green house gases. Other than the environmental benefits of photovoltaic energy, transitioning to this type of energy would help out many people around the world. Photovoltaic energy is inexpensive and efficient, allowing more people to use it. This energy is cerated directly from the sun. For example: When sulight strikes solar cells, the light makes the cells go loose. Electrons then go to the top, or surface of the panel. This makes the electoral balance in the panel uneven. If the panels are then connected to a wire, the positive and negative energy will go through the wires and create electricity. This energy only requires a certain amount of sunlight to produce energy, and afterwards, it can even be used in the dark, with recharging in the sun, of course. The electricity from photovoltaic cells can be converted into phones, lights, calculators, even cars! All it takes to make these panels is a little amount of coal, but in the long run it will be worth having them around. So we don’t have to run out of energy, but it's up to you to make photovoltaic energy the energy you rely on and trust.
