1

Cars: Double the fuel efficiency of all cars worldwide and halve the number of miles traveled by cars each year.

Improve technology in vehicles. Phase out inefficient vehicles. Improve city design and mass transit.

2

Buildings: Reduce energy use in all buildings 25%.

Improve insulation and building design. Improve efficiency of heating and cooling, lighting, and appliances.

3

Coal efficiency: Improve coal power plant efficiency from the current 40% to 60%.

Improve technology for burning coal and converting it to electricity.

4

Solar energy: Increase photovoltaic solar power capacity.

Increase today’s photovoltaic capacity by 700 times. This would require 2 million hectares of land (see Section 2.6).

5

Wind energy: Increase wind power capacity.

Increase today’s wind capacity by about 40 times. This would require 30 million hectares (74 million acres) of land (see Section 4.5).

6

Deforestation: Reverse deforestation in the tropics.

Provide economic alternatives to cutting forests for developing countries. Reduce demand for forest products in developed countries by supporting recycling and more efficient manufacturing.
