IEA: Renewables To Equal Coal by 2035 | American Solar Energy Society

Water is essential to the production of energy, and the energy sector already accounts for 15% of
the world's total water use. Its needs are set to grow, making water an increasingly important
criterion for assessing the viability of energy projects. In some regions, water constraints are already
affecting the reliability of existing operations and they will introduce additional costs. Expanding
power generation and biofuels output underpin an 85% increase in the amount consumed (the
volume of water that is not returned to its source after use) through to 2035.

"Our analysis shows that in the absence of a concerted policy push, two-thirds of the economically
viable potential to improve energy efficiency will remain unrealised through to 2035. Action to
improve energy efficiency could delay the complete `lock-in' of the allowable emissions of carbon
dioxide under a 2°C trajectory - which is currently set to happen in 2017 - until 2022, buying time to
secure a much-needed global climate agreement. It would also bring substantial energy security and
economic benefits, including cutting fuel bills by 20% on average," said Fatih Birol, IEA Chief
Economist and the WEO's lead author.

WEO-2012 presents the results of an Efficient World Scenario, which shows what energy efficiency
improvements can be achieved simply by adopting measures that are justified in economic terms.
Greater efforts on energy efficiency would cut the growth in global energy demand by half. Global oil
demand would peak before 2020 and be almost 13 mb/d lower by 2035, a reduction equal to the
current production of Russia and Norway combined. The accrued resources would facilitate a
gradual reorientation of the global economy, boosting cumulative economic output to 2035 by
$18 trillion, with the biggest gains in India, China, the United States and Europe.
