erence Scenario. In the Reference Scenario, Russian gas-fired generation nearly doubles between 2002 and 2030 and its share increases from 43% to 53%. In the Alternative Policy Scenario, it increases at a much slower pace and its share increases only slightly, because electricity demand is much lower and because nuclear power substitutes for gas. Global electricity generation from fuel cells using hydrogen from reformed natural gas is 530 TWh, twice as high as in the Reference Scenario in 2030. Nuclear power capacity expands to 428 GW in 2030, about 50 GW more than in the Reference Scenario. Nuclear power production is 14% higher. The largest increases in output occur outside the OECD, notably in Russia where nuclear production is 40% higher in 2030 compared with the Reference Scenario. Nuclear production rises by 16% in China and by 21% in India. All three countries have ambitious nuclear programmes and plans for nuclear plant construction.

OUTLOOK FOR GLOBAL INVESTMENT IN ELECTRICITY INFRASTRUCTURE In the Alternative Policy Scenario, hydroelectric generation in 2030 is slightly higher than in the Reference Scenario. Hydropower's share in world generation drops from 16% in 2002 to 13% in 2030 in the Reference Scenario, while its share falls only by one percentage point, to 15%, in the Alternative Policy Scenario. The share of non-hydro renewables increases much more, from 6% in 2030 in the Reference Scenario to 9% in the Alternative Scenario. The strongest increase is in OECD Europe, driven by the European Union's strong support for renewables. Electricity generation using non-hydro renewables is almost ten times higher in 2030 in the Alternative Policy Scenario than in 2002, and more than a third higher than in the Reference Scenario. In the Alternative Policy Scenario, worldwide cumulative investment requirements for electricity supply infrastructure over 2002-30 are just over USD 1.5 trillion (in year-20
