Madison Smith- Solar Energy-- Life Saver or Ticking Time Bomb?
In recent years, there has been a rise in the use of “clean” energy sources. Unlike fossil fuels and natural gas, renewable energy does not have to be burnt and has little to no greenhouse gas emissions. One of the most popular sources of renewable energy comes from space.
Solar power is on the cusp of explosion. As they continue to become more affordable and more efficient, homeowners are beginning to invest in solar panels as a clean energy source for their homes. (It also doesn’t hurt that the government provides a large tax cut for citizens who install solar panels on their houses.) With virtually zero emissions, a high energy output, a permanent source of solar radiation, and a 30-year lifespan, solar power seems like the perfect replacement for coal-burning power plants. Unfortunately, there are a few detrimental downsides, not to the energy itself, but to the solar panels that harness the sunlight.
Solar panels are constructed from hazardous materials such as sulfuric acid, phosphine gas, lead, chromium, and cadmium. Their composition means they cannot be recycled or stored in landfills (without protection against contamination). If solar panels are disposed of incorrectly, the lead can cause nervous system damage. Furthermore, chromium and cadmium (known carcinogens) can leak into drinking water supplies if a plan for safe disposal is not implemented. This is very discouraging because most countries (with the exception of European countries) that are advocates and avid users of solar energy have no contingency plan for solar panel disposal. Well, at least they don’t contribute to global warming, right?
The use of solar energy does not contribute to increasing greenhouse gas emissions... But in the past, the production of solar panels almost emitted enough carbon dioxide to cancel out the clean energy it provided. Technological developments have drastically reduced solar panel production carbon emissions, however, the production of the panels increase the production of nitrogen triflouride, a greenhouse gas 17,200 times more potent than carbon dioxide.
Now that you know a few more facts about solar energy, here’s a few things to think about:
Do the benefits of solar energy outweigh the downfalls?
Is there a “cleaner” way to meet the global energy demand?
What can be done to make solar power safer for the environment?
