question
Along with many other governmental reforms that began in 1994, the electrical plant just outside Soweto was closed in 2000 and other plants were brought into use. Some parts of Soweto were then wired for electricity. It is estimated, however, that only about 30% of the more than 1 million black inhabitants have electricity in their homes; the remainder cannot afford the costs involved or live in areas that have no electrical access. So, they probably use ________ for fuel.
answer
wood and coal
question
The major long-term global problem with using coal to generate electricity is the ________.
answer
carbon dioxide released
question
One of the promises made by the government in 1994 was "free electricity." Since 2001 the government has provided a small amount, 50 Kilowatt hours per month, free to each household. Beyond that, a household must pay for the electricity that it uses. Many people would prefer a flat-rate pricing system, where each household throughout greater Johannesburg would pay the same rate each month. This would mean that ________.
answer
with less incentive to keep electric usage low, environmental issues related to the generation of electricity would worsen
question
What is energy intensity?
answer
the energy use per dollar of the Gross Domestic Product (GDP)
question
How is the energy produced by nuclear fission used to produce electricity?
answer
Water in the containment vessel is kept under high pressure and heat from the fission reactions that heat it to well over boiling. This is then used to boil another loop of water, which turns a turbine that drives a generator and makes electricity.
