Have you ever wondered the world without the sources of energy? Today the sources we use are non renewable sources which will come to an end after a certain period of time. It is therefore very important for us to save energy as much as possible.
The most common ways of attaining a life off the grid is by the use of solar panels, hydropower and wind turbines or even good, old-fashioned wind mills. These items are still expensive to buy and very expensive to have installed. A recent study in the UK estimated that it would take 10 years to recoup the investment of a professional installation of energy-making devices.
If you buy a 120 watt solar panel from the Internet you will pay something like $1,100 for a ready to install unit. That’s $9.30 per watt when you reduce the efficiency by 15%.
The next frontier is Water Turbines.These are similar to wind turbines and are placed in the water currents. The current spins the turbine to produce electricity. This technology dates back to the Romans. Nova Scotia has a turbine producing 20 MW since 1984. La Rance barrage in Normandy puts out 240 MW and was installed in 1966. In 2007 New York City tried installing turbines in the Hudson river. The current was so strong it was snapping the 20 foot blades. In 2010 using what they have learned a new project is under way to install 30 underwater turbines in the East river between Queens and Roosevelt Island. The completion will be sometime in 2011 if all goes according to schedule.
There’s also power supplier advocate and writer Al Weinrub. He argues that decentralized energy, or putting renewable systems in as many places in a community as possible, generates wealth, spurs economic revitalization and helps adapt to climate change.
When you look at what is happening around the developed world, you see very similar economic issues, mostly tied to debt. Along with Greece, other European countries are also struggling with the real potential of economic calamity.
If you are planning to build you house, then plenty of water is required for construction. your house is a small fraction of construction industry. Uncounted commercial buildings, apartments, public places cannot come into existence without water. Construction industry cannot work without water.
Aside from those ideas above, one factor that helps me on how to save energy in my home is by changing the existing paint of my house into lighter colors. Light colors can be a big help when it comes to using light in your home, especially during the day. But one important thing that I can recommend which I’m also using is the use of energy yardstick. It helps me a lot in terms of the dos and don’ts of saving energy in my home.
