Compact fluorescent light bulb: 1/4 of the electricity of an incandescent bulb: 1/4 of 40 watts =0.25 x 40 =10 watts
 * 1.** Incandescent bulb: 40-watts

Energy saved:Incandescent bulb-Compact fluorescent bulb: 40 watts-10 watts =30 watts

Energy saved by switching 25 40-watt bulbs: 30 watts x 25=750 watts

Therefore, 750 watts of energy would be saved by switching 25 40-watt incandescent light bulbs to 25 10-watt fluorescent light bulbs.

**2.** Industrial Job Cost : $75 000
Green Job Cost : 80% of Industrial Job Cost = 0.8 x $75 000 = $60 000

=
Therefore, $750 000 000 would be saved by creating 50 000 green jobs instead of industrial jobs. ===== 

211 1976 3964 306 +2120 ¯¯¯¯¯¯ 8557 MW If x = the total amount of energy generated in Ontario: 1/6 x = 8557 x = 6 (8557) = 51 342 MW Therefore, Ontario generates about 51 342 MW of electricity.
 * 3.** Total coal-generated energy:


 * 4.** Ontario Generation total Power Capacity: 22 000 MW

Gas fired Stations generate approx. 6 % of Ontario's electric supply. Gas Fired Station energy:

22 000 MW x 6 % = 22 000 MW x 0.06 = 1320 MW

Total Fossil fuel generated electricity equals gas-fired electricity + coal generated electricity. Total Fossil fuel generated electricity: 1320 +8557 ¯¯¯¯¯¯ 9877 MW Nuclear and Hydrogenerated electricity equals total capacity - total fossil fuel generated electricity. 22 000 -9 877 ¯¯¯¯¯¯ 12 123 MW

Therefore 12 123 MW are generated by Nuclear or hydro stations, and 1320 MW are generated by Gas Fired Stations.

Therefore, approximately 3% of the generating capacity in 2003 was renewable.
 * 5.** Generating Capacity in 2003: 1000/30 000 = approx. 0.03 = 3%

Signed contracts from 2010 goal: 1300/2700 = approx. 0.48 = 48% Therefore, approximately 48% of the goal for 2010 has been obtained or signed by the government.
