Big OPEC oil producer is spending billions to go green

The country, a core member of OPEC, plans to invest $163 billion to boost its use of alternative energy over the next three decades.  That should increase clean energy's share of UAE consumption from 25% to 50% by 2050. The country also hopes to increase energy efficiency by 40% over the same period.UAE vice president and ruler of Dubai, Sheikh Mohammed bin Rashid Al Maktoum, said the new energy strategy should save the emirates $190 billion over three decades.  Low oil prices are forcing major producers, including Saudi Arabia, to rethink their economic strategies.
