The modern world is presenting humanity with dozens of new challenges. As natural resources run out, it’s becoming incredibly important for people to find new ways to power the world. Currently, most of the world’s electricity is generated from unsustainable sources. This means that, eventually, the materials won’t exist anymore. Unfortunately, this isn’t the end of the badness, as these fuels are also very bad for the environment. Renewable energy is already here, though; it just needs to get around. This post will be going through just a few of the methods being used, today.
Water provides for a large portion of the world’s responsibly sourced power. Dams, offshore generators, and even mills can be used to make power with water. Thanks to gravity, water is affected by things like elevation and the moon. This creates movements, which can be harvested of their energy. Power is generated when the power of the water forces a turbine to turn. An inverter converts the energy so that it can be stored and used on the grid. Unfortunately, though, these sorts of systems are damaging in their own right. They can be very dangerous for fish which don’t understand how to get around them. And, larger animals have even been found to get caught. Along with this, hydropower isn’t exactly the most efficient around. Instead, it’s better to look at some other methods.
The next option on this list is the most promising in the current climate. Solar power is already being widely used in some areas. Companies like Apple and Tesla are pioneering use of this sort of resource within the technology industry. And, of course, a lot of governments are pushing for more people to take on this sort of power generation within their homes. But, how does solar energy work? The panels you see dotted on some rooftops are actually made of loads of smaller cells. These cells can generate power from light by allowing it to knock the electrons from atoms. In the process, a small amount of power is made. Of course, though, everything has its drawbacks. At this current point, it’s hard to generate much power in anything less than clear skies. This will improve in the coming years, though.
Last, on this list, it’s time to look at wind. Wind is an extremely powerful force; and, it’s one that humans are already doing well to harness. Much like with hydro power, wind turbines generate power when they are turned by a natural force. Wind moves a large propellor-like turbine, which in turn creates power. Of course, like the other two options, wind power has its drawbacks. Unfortunately, they can make it hard for certain birds to navigate. And, most people don’t like the way they look. But, this form of power has a good heritage. People used to use windmills to grind wheat to make flour; long before machines were invented.
Hopefully, this will give you a good idea of what’s being used to make the world a greener place. This sort of effort is being conducted everywhere. And, it’s making a difference already. But, that difference needs to get much larger before people can rest easy.
