There are many different types of renewable energy and it is becoming more and more important as governments start to look at ways of maintaining the environment in a more sustainable form. Combined, these resources create a sustainable and easily accessible form of energy for anyone and everyone. Depending upon the environment of your state/country, you should be able to use at least one of these forms of renewable energy.
This is the most popular, as sunlight is available everywhere all across the world. All you need is unobstructed space in order to capture the light and you're ready. Because of this, many governments have started focusing their attentions towards this largely untapped resource. The only con is that solar is weather and light dependent. As the technology increases, advances are allowing more and more people to go solar. Soon it will be one of the most predominant forms of any kind of energy available.
Many countries are now looking towards turbine energy as it provides an enormous source of energy. With their large turbines held up high, they are spun by the gusts of wind. They require a lot of space, but wind farms are becoming a far more common occurrence day-by-day. One of the big problems with wind farms is that they have to be in an area known for wind, but with them being held up high they can easily manage this. Some people are also against the way they look, but many are now growing more tolerant towards their appearance as they become a permanent fixture of the landscape. With their use growing year-by-year, they offer a great energy resource for many.
This consists of using the energy from waves to power the turbine engines. Many are now using this along coastal areas around the world. As the waves come in the motion is used, as with the others, to power the turbines and generate energy for the surrounding area, which means they are great for docklands. An issue with this is that it needs to be by the water in order for it to get the waves it needs, a luxury many may not have. The waves also need to be fairly strong to keep it powered. Either way, many areas find that it is a positive asset to their community when it does work well offering the energy that's needed.
You can also find people using biomass (plant extracts) to fuel their energy sources amongst a number of other things. With all of these resources in mind, it's easy to see why so many are turning to renewable resources and what they can offer.
