Reference Scenario<br />

Additional demand in the Alternative Policy Scenario<br />

electricity-only power plants and in liquid biofuels for transport. Most of the<br />

increase in biofuels production over and above the Reference Scenario occurs<br />

in Europe and the United States.<br />

Electricity Use and Generation<br />

The policies on energy efficiency and conservation taken into consideration in<br />

the Alternative Policy Scenario reduce global electricity consumption by 12%<br />

in 2030 vis-à-vis the Reference Scenario. More efficient appliances in the<br />

residential and services sectors account for most of these savings and more<br />

efficient motors in industry for most of the rest. Electricity intensity –<br />

consumption per unit of GDP – falls much faster over 2005-2030 as a result:<br />

by 1.7% per year, compared with 1.2% in the Reference Scenario.<br />

Lower electricity demand and measures to boost the thermal efficiency of power<br />

stations reduce demand for fossil fuels as inputs to generation. As a result of these<br />

measures and other policies to boost non-fossil fuels and technologies, the fuel mix<br />

in power generation changes markedly (Figure 1.20). The share of coal in 2030<br />

drops most relative to the Reference Scenario, from 45% to 34%. The absolute<br />

amount of coal burned in power stations in 2030 is around two-thirds that in the<br />

Reference Scenario. The share of gas in 2030 also falls, from 23% to 21%. In<br />

contrast, the shares of nuclear power and renewables increase significantly.<br />

<strong>Energy</strong> Investment<br />

The policies and measures analysed in the Alternative Policy Scenario lead to<br />

a major shift in the pattern of energy investment. Consumers – households and<br />
