Clean and Abundant Power Sources: Our Legacy for the Future

The term 'Clean Energy' implies a lack of dirt. I guess that is true of the sun and wind. For example wind energy is supplied by a turbine which is mounted on a pillar up high to catch the wind that doesn't reach down as far as the ground. The only source of the power, is the wind, which is clean and free. There is of course the manufacture of the turbine to take into consideration but once you have your turbine , it should be low cost to maintain and as long as there is wind to blow, there will be energy . Wind energy is not a new thing, there have been windmills for centuries but the energy they provided was much more centralized. Wind turbines feed into the national grid and so benefit many more people. Then there is Solar energy - via the solar panel - which is also very clean and abundant providing we have daylight. The newer Solar cells are photo-Voltaic and more efficient in less strong sunshine ,it doesn't even need to be a very sunny day for them to be effective at harvesting power from the sun. Solar panels can fit on the roof and their energy can be fed into the building on which they are mounted, while excess can once again feed into the national grid. Together they can help to reduce the need for fossil fuels, they do not pollute the air,water or land and they can be sited conveniently.
