Portable Solar Battery Chargers

Cost has been the biggest barrier to widespread adoption of solar technology. Traditional silicon-wafer solar panels require a complex, time-consuming manufacturing process that drives up the per-watt cost of electricity. Cost: Initial start-up cost of solar power is considerable. While a single solar panel that gives emergency back-up energy is reasonable, providing an entire photovoltaic cell array to power your home will cost thousands of dollars.

Solar power homes require a lot of sunlight year if you want it to be worth your time and effort. Solar panels will still provide your home with some power through the elements of trees, rain and clouds but it won't be as good as it could be. Solar power homes can do the trick for us if we refrain from using other efficient forms of energy. They will be able to help us make a new world and with this solar power we will be able to add less pollution to our system for the coming generations. Solar power homes are the most recent technological innovations in the field of engineering and science. People have long searched for fresh ways to live economically amidst the crisis occurring in the country.

Installing solar power for homes saves you money. No more need to worry about the huge energy rate rises ahead. Installing small-scale devices has just become a lot easier for homeowners. Micro generation enables the concerned individual to become an active citizen in tackling global warming.

Installing solar power maintains the well being of our precious planet. It reduces the emission rates of CO2 into our environment. Install a solar power system in your home and witness its benefits. Install doors made of metal that are insulated, so that the cold stays out and the warm gets in and stays put. Make sure your doors are closed tight at the time of day that the sun comes in; this insures that the heat remains in the house for a longer period of time.

For example, a charge controller would be recommended if the R15-1200 (with 1.2 Amps) were connected to a battery that is less than 120 Amp-hours. Consult the battery manufacturer for complete battery information and recommendations. I charged it up for half a day and it seemed to never want to die! I am sending back my original IPOD battery for recycling. After rummaging around in your glove compartment for a bit, you retrieve your solar-powered battery charger. You plug the USB cable from the charger into your cell phone, flip the charger over so that its small solar panel faces skyward, find your cell phone signal, place the whole setup on a stump, kick back and wait.

Wind turbines produced a measly 3 percent. Wind is nothing but air in motion which is caused by the heating of the earth's surface by the sun. However, as the earth's surface consist of plain land, hills, oceans, etc that do not lie in the same level, the absorption of the heat varies a lot. Wind energy can be attained by installing wind propellers connected to a generator. Hydroelectric energy may only be available if you have a nearby stream, creek, or river.

Wind powered electrical systems produce about 9-10 times the amount of electricity that solar energy produces. The only downside is if your area does not get more than 8-10 mph average winds then there is a possibility that you would not immediately be able to get your investment back. Wind energy and alternative energy sources will work best when understood on both macro and micro scales.

Small and mid size organizations might benefit more from a small wind turbine as opposed to depending on the power company to secure alternative energies for them. Wind energy has a lot of potential in the long term, experts predict the technical potential of wind energy is five times total current global energy production, or 40 times current electricity demand.
