Well lights in the house, garden lights and your water heater can all be powered by solar energy.
You can also have a battery that is charged by solar energy and other appliance can then be connected to this battery.
Yes, you can. You could also save energy by buying energy efficient appliances and using energy efficient lightbulbs.
Yes, the electric power grid could be powered by electric power generated through nuclear energy.
The negative environmental impact of an electric car could be minimize by efficient recycling of the auto when scrapped.
Energy efficient refrigerators use 75% less energy than one made in the 1970's. You could save up to $100 a year.
The resistance is decided by the designer. In principle the stator could have zero resistance. The actual resistance depends on how efficient the motor is required to be. Efficiency has to be traded against the mass and cost of the motor, because lower resistance for greater efficiency requires thicker, heavier copper wire. In practical designs, higher-powered motors are usually made more efficient in order to reduce the energy wasted in the resistance. For low-powered motors it isn't worth it because they don't waste much energy anyway.
Anything that makes energy. Mitochondria makes energy for the cell. You could use a nuclear powered plant.
No. They're too far away.
There are several different options available to homeowners that are looking for efficient home energy heating. A person could search the categories "types of efficient home energy heating" in order to narrow down the particular type of product or service that would be of interest. Once you know which types of products or service you are most interested in this would help to specifically design the proper search question. For example, "what is the cost of "this" system or, "is "type" system available in my area.
There are tools you can purchase at the hardware store to measure the amount of sunlight energy that is entering through your window. Energy less than 2 kilowatts is considered energy efficient. You could also consult a service professional based on the type of windows you have.
Yes, hydro (kinetic) energy can be used to generate electricity. There are many electric vehicles, including trains.
Have a solar powered water pump will save you on energy cost. You can order one online at www.siliconsolar.com.
We could stop working on wind turbines and other renewable energy sources. We could stop trying to make machinery more energy efficient. We could vote republican.
