It is expected that, by 2030, the demand will increase to about 120 GW per year, approximately three times the 2010 load. Satisfying this demand will require a significant investment in the power grid at an estimated cost, over the next 10 years, ofSAR (Saudi Arabia Riyal) 500 billion. Existing power plants rely on oil and natural gas, it is anticipated that meeting the demand in 2030 will consume 3 million barrels ofoil each day, which significantly impacting the economy by reducing the country's income from oil exports, which is a hot button for Saudi decision makers. This paper reviews the responses of various countries in meeting their loads, and therefore, draws recommendations for some resources that should, and should not, be considered best-candidate options for Saudi Arabia economically, technically and environmentally. The discussion primarily examines renewable and nuclear resources.展开更多
