Pro And Cons Of Renewable Energy

Renewable energies are energy sources that are alternatives to fossil fuels and can be replenished. Everyday industrialized countries pollute the Earth’s atmosphere with fossil fuel byproducts, like CO2, creating adverse effects such as climate change and global warming. From big businesses on an industrial scale to single individuals we all play a part in pollution, with things ranging from factories to automobiles. This is a big concern, considering many people would like to preserve the earth for generations to come. Due to this fact scientists have started to find new ways to provide cleaner and alternative energies to power the Earth. The history of using energies dates way back into the neolithic era when early humans started to

It accounts for over 16 percent of the world 's net electricity production. The most common method of hydropower energy involves the building of dams on rivers and releasing water from a reservoir to drive turbines.(POWERTECH). The second most used and fastest growing renewable energy is wind power. Wind power uses wind to spin a turbine creating electricity. If used in areas with high concentrations of wind it the amount of potential energy to be harnessed is great. The third most used is solar energy. Solar energy uses solar panels or like devices to harness the Sun 's heat and light energy and turn that into usable electrical

One disadvantage with renewable energy is that it is difficult to generate as much electricity that fossil fuel generates. This means that we need to reduce the amount of energy we use or simply build more renewable energy facilities. Another disadvantage of renewable energy sources is reliability. Renewable energy relies on the weather for its source of power. Hydro generators need flowing water, wind turbines need wind to turn the blades, and solar panels need clear skies and sunlight to collect heat and make electricity.(SOLARSCHOOLS). When these are unavailable we can 't attain energy from them. The current cost of renewable energy technology is also more expensive than fossil fuel technology. This is because it is a newer technology and as such has extremely large capital
