For a state that was importing almost 90% foreign energy, this is a giant step toward energy dependency. Full story here.

Also notable – In Israel 90% of homes already utilize solar hot water heaters since an energy crisis in the 1960s. In fact, according to this story 60% of Israelis were already using the sun to heat their water. Spain is another country with this policy. See story here.
