Your daily electricity needs, generally on your electric bill, or add up the wattage of each item you wish to run times the number of hours you wish to run it.

I would like to know more about renewable energy because my country has a lot of electric power problem and more so to the rural areas. These are the people who can not afford to pay initial cost of solar panels.
Please help
