Renewable Energy Sources

1. Pros

   • Renewable energy sources regenerate quickly
     • Renewable energy sources have an advantage over non renewable sources as it can be used without worrying about conserving it
     • They can be used forever, unlike non-renewable sources, since they can regenerate
   • Most of renewable energy sources can be used without polluting the environment
     • Non-renewable energy sources, like coal and petroleum, emit harmful gasses like carbon dioxide
       • Carbon dioxide contributes to global warming, which affects the environment and our health
       • "Coal makes us sick. Oil makes us sick. It's global warming. It's ruining our country. It's ruining our world." Quote by Harry Reid
   • Renewable energy sources are mostly readily available around the world
     • Non-renewable energy like fossil fuels are not available everywhere. They have to be mined from the ground
       • Most non-renewable sources are hard to obtain. Natural gas, for example, must be taken from the ground and cannot be found everywhere
         • Renewable sources, however, are easy to obtain and can be found almost anywhere. Solar power, for example, only needs sunlight. which can be found anywhere
   • Usually, renewable energy sources produce more energy than it takes to create the method for using the energy
     • Some renewable energy sources may be expensive to buy and use a lot of energy initially, but overtime, they create more money and energy than it used
       • One example is solar panels. They use a lot of energy to create it, but it usually takes 1 to 4 years for solar panels to make as much energy as it took to create them. However, solar panels usually last 20 to 24 years, making much more
   • Some renewable sources are now cheaper than non-renewable sources, like coal
     • Coal fired plants costs a lot when climate change costs and other health impacts are considered
       • “Burning coal is a very costly way to make electricity. There are more efficient and sustainable ways to get power,” said Dr. Laurie Johnson. “We can reduce health and climate change costs while reducing the dangerous carbon pollution driving global warming.”
   • Using renewable energy more will help economic growth and make more jobs
     • If more and more people invested in renewable energy, than there will have to be more people to create the machines that use renewable sources

2. Cons

   • They often do not produce as much energy as non-renewable sources
     • Solar panels for example, do not create that much energy per cell. They need a large amount to make enough energy. The maximum efficiency solar panels have reached is 40%
   • Cost for most systems are high
     • Water dams and wind turbines, for example, require a lot of money to make and maintain
   • Most are not reliable
     • Renewable energy sources rely on nature. Because of this, it is not always reliable
       • Wind turbines, for example, need win to operate, and the wind has to be a within a certain range
   • Some renewable energy systems can ruin a landscape
     • Wind turbines can ruin the landscape. Solar panels can also ruin the look of a house
     • Wind turbines also make a lot of noise, which can disturb people
   • Some can also have impacts on certain animals
     • Wind turbines can kill birds that try to fly rhough the baldes
     • Water dams can disrupt the ecosystem of fish and marine animals
