Denmark is blessed with an abundance of wind and became a pioneer and a leader in wind power technology in the world.  It was reported that 43.6% of electricity was generated by wind power in Denmark in 2017.   The wind turbines in Denmark generated as much as 14,700 GWh (giga-watt-hour) of electricity in a year.

1. How much wind power in GWh did Denmark generate in one month during 2017?
2. How much wind power in GWh did Denmark generate in one day during 2017? (Use 1 month = 30 days) Round to the nearest one.
3. With 1 GWh of electricity,  about 33,400 households* in the United States can use electricity for a day.  There are about 1,360,000 households in Connecticut.  Is the wind power in Denmerk big enough to supply electricity to the entire household in Connecticut or not? Explain.

* According to U.S. EIA, the average annual electricity consumption for a U.S. residential utility customer was 897 kWh per month in 2016 (EIA, 2017)

1. 14,700 ÷ 12 = 1,225 (GWh)

2. 1,225 ÷ 4 = 40.83… ⇨41 (GWh)

3. Yes. 33,4000 x 41 = 1,369,400

1,369,400 > 1,360,000
