  AFAIK the building code requires all residential buildings to be built with solar power heaters, they are usually augmented by either an electrical heating element within the heater itself or by a secondary gas/fuel oil heater. These heaters have been used since the 50's it's nothing more than a few pipes running through a sheet metal frame with a glass cover to force a greenhouse effect they are highly effective and extremely cheap to produce those panels cost near nothing and were implemented very early on when Israel had very little access to overseas fuel sources. Israel didn't had access to regional oil until the the Iranian coup in 1953, it lost its access to Iranian oil in 1979 with the Iranian revolution, however the same year Israel and Egypt signed the camp david accords and Egypt started supplying Israel with Oil starting January of 1980. Ironically the Iranian revolution quite likely had quite a positive effect on Israel as it quite likely pushed them to finalize the negotiations with Egypt and to sign an agreement as fast as possible in order regain some access to a regional oil source.
