Definitions
Stationary power comprises traditional uses of electricity as well as power for heating and cooling of residential and commercial buildings presently provided by non-renewables (such as oil and gas) and does not include power for transportation (e.g. cars, trucks, buses, trains, air travel), although some forms of transportation ought to be powered by electricity such as trains.) The target should include plans to electrify most modes of public transit
Renewable energy is produced from resources such as plants, sun, wave, tides and wind but these are not necessarily zero carbon. Natural gas is NOT renewable. Hydroelectric power from dams can produce carbon dioxide and methane due to decomposing plant material: http://www.newscientist.com/article/dn7046-hydroelectric-powers-dirty-se...
Zero carbon sources include:
- wind turbines (both land based and offshore) but not natural gas
- bio-gas insofar as it is zero carbon
- solar PV, solar thermal, and concentrating solar thermal power (CSP)
- geo-thermal heating, geo-thermal electricity
- run-of-river hydro
- nuclear power from existing, unrefurbished plants (given the significant risks of operating and disposing of wastes and the considerable costs and time to construct them, new or refurbished nuclear power plants should not be included)
- any other source that does not generate carbon as a by-product of its generation
