Energy efficiency is the key to survival, Canada has terrific wind resources much like Denmark, only Denmark has made it a reality and we have not. There they have a number of wind farms filled with turbines than collectively can provide electricity for thousands of homes. An individual turbine can supply electricity for a thousand homes. The tower on which they stand weight about 200 tons. The turbines and blades themselves weight tons. I can’t figure out why we don’t take advantage of the technology and build comparable wind farms on our Atlantic coast.

Another type of renewable resource was a stretch of land at Saguaro, in the Southwest of the United States which houses oil containing tubes that run alongside a series of mirrors that reflects solar energy. As the oil runs down a stretch these mirrors heat it. The heated oil then runs turbines to produce electricity and the same oil can be funneled back for reuse. This project was funded until Regan got into office but then it lost favour with Republican leaders who were still bent on more conventional means of generate electricity.

Another renewable resource is geothermal energy, just drill a small hole in some areas of Iceland and a column of steam spews upward, enough to provide the force to run turbines and create electricity and then the water left behind goes off to heat homes and is then used to provide drinking water for the homes there once it is cooled. Scientists there are considering not having to drill as deep to obtain the vapour that is caused by underlying volcanic magma. Still the amount of vapour produced.

Sky lights produce five times of light then side windows, so there is a housing design available to maximize the number of skylights in a house. Obviously with the increased illumination in the house there would be a substantial decrease in the use of light bulbs that have been a cause of global warming. However residences that would optimize this kind of natural lighting cannot be built everywhere.

Much of our consumption has to be reduced because if everyone had to use as much as us we would need several planets. Wind kales can be used to remove stale air and restore fresh air with a reduction in energy demand in Europe. We can also incorporate workspace into houses that can cut down on the use of fossil fuels. Energy efficiency can even be introduced further into appliances like refrigerators that have not had an energy efficient design. They were never really designed so that the cold air would not just fall to the floor if you would open the door. There is a current prototype out there with an opening in its top, that is more energy efficient. Perhaps that will lead the way for scientists to develop other more energy efficient appliances for the home and business.
