Everybody wants green energy. Being able to get the power we need without damaging the environment is an obvious goal – but what’s the best way to achieve it? Should we be opting for wind farms, hydroelectricity, or solar energy as alternative power?

Renewable Energy is energy created from resources that are regenerative – or renewable – meaning they cannot be depleted. These resources are safe for our environment and produce energy without the harmful pollutants and emissions associated with fossil-fuels.

Wind farms often receive a bad press, especially when they’re situated near homes or in popular hiking areas. They can make a lot of noise and because they have to be placed on skylines for maximum efficiency they often spoil views. Offshore wind farms are less problematic in this way and can take advantage of fierce sea winds, increasing their output, but they rely on a nation having a lot of suitable coastline.

While the Netherlands does very well with its wind farms, the US is, considering the comparative size of its population, at a distinct disadvantage. For the home-owner, small wind-powered generators are available, but they’re not very efficient and often result in complaints from neighbors.

Hydroelectricity is a much more effective way of generating power, using the natural energy of rivers or tidal forces. However, there are a limited number of suitable locations for hydroelectric generators, and often these are in areas which already provide fertile farmland, so a lot of people have to be displaced and lose their land in order for them to be built. They can also have a damaging impact on local wildlife.

Of these three major options, only solar energy as alternative power passes the test of being truly non-polluting, practical and easy to access. Modern solar panels can still function effectively even in areas where it’s frequently cloudy. They don’t get in anyone’s way and, once installed, they require very little maintenance. For these reasons, the greenest way to generate the power we need is by harnessing the power of the sun.
