But one of the biggest arguments against renewable energy is that these sources cannot be stored or contained like fossil fuels such as coal, oil, or natural gas. In addition, even if solar energy can generate sizable amounts of electricity, what happens when the sun doesn't shine? And what happens if the wind doesn't blow strong enough to propel wind turbines? And how do you generate electricity with renewables at night, when the sun doesn't shine and wind speeds traditionally die down? Some people have taken upon themselves to install deep-cycle battery packs in their green homes, and while they can be used to store renewable energy sources from solar and wind, they are bulky, heavy, and require a lot of space to be used effectively.
Enter Elon Musk, the founder and CEO of Tesla Motors. He says he has come up with a solution to store said energy that is not only smaller and more efficient than current batteries but lighter on the carbon footprint and the pocketbook. But is it a green energy dream come true that will revolutionize the energy world as we know it or just really good marketing hype?
