In Israel 90% of homes have solar heaters.

Would not one wonder that in Israel, 90% of homes have solar water heaters installed. When viewed from above, the Jerusalem often glitters with the shine of the thousands of solar heaters that adorn rooftops. These heaters were first installed when the country experienced a fuel supply crisis in the early 1950s. The government responded by severely restricting the times when water could be heated. Israelis in turn responded by purchasing huge quantities of solar water heaters. By 1983, 60% of the population heated their water with the sun. A law was eventually passed requiring the installation of solar water heaters. Hawaii has enacted a law that requires all new homes to install solar water heaters. Eventually, Hawaii may have as many water heaters as Israel. In 2005, Spain became the second country (after Israel) to require solar water heaters. It also became the first country to require the installation of solar cells for electricity generation in new buildings.

In many climates, a solar heating system can provide a very high percentage (50% to 75%) of domestic hot water energy. In many northern European countries, solar power is used not only to heat water, but also to provide 15 to 25% of home heating energy. There is need to create awareness on effects of climate change and rising energy costs. There are many solar thermal
systems which are being widely used in both residential and commercial applications to provide hot water, space heating, industrial hot water and even air-conditioning. Installing just one solar thermal collector can reduce CO2 levels as much as planting more than 200 trees and is the perfect choice for people wanting to become part of the SOLUTION by reducing their carbon footprint.
India and Pakistan can also benefit as they have enough Sun shine. Installing Solar heater can reduce there dependence on fossil fuels and the general populace should benefit from this solar heating.
