Energy

Question 0

Energy efficiency of coal-fired power

Answer 0

Efficiency gains in electricity generation from coal-fired power stations will play a crucial part in reducing CO2 emissions at a global level.

Question 1

Energy Efficiency of Nuclear Power

Answer 1

The main benefits of nuclear power are that is it more efficient than burning fossil fuels as the amount of energy released from uranium per gram is much more than that of fuels such as oil or coal; approximately 8,000 times more efficient in fact. Despite there being far less uranium reserves in the world compared to fossil fuel reserves, the potential amount of energy generated is still greater and there are no greenhouse gases released into the atmosphere. The minimal greenhouse gas emissions is probably the most appealing benefit of nuclear power as global warming is a very well-known and discussed issue nowadays.

Question 2

Waste products of coal and nuclear power

Answer 2

waste from conversion/generation of electric and mining of raw materials

Question 3

Reasons for changes in global oil consumption beginning in 1950

Answer 3

more vehicles means more use of gasoline and increase use of oil consumption

Question 4

Types of mining

Answer 4

Surface mining–contour, strip, open pit, mountain top removal

Question 5

Types of ACTIVE solar systems

Answer 5

Converts 1. Photovoltaic cells
2. Condenser mirrors(some by PV cells)
If it is converting the energy it is active

Question 6

Advantages and disadvantages of natural gas as fuel

Answer 6

Question 7

Process of crude oil refining

Answer 7

n/a

Question 8

U.S storage of Nuclear Waste

Answer 8

It is currently being stored primarily at sites where it was generated. After spending decades and billions of dollars to research potential sites for a permanent disposal site, including at the Yucca Mountain site in Nevada, the nation remains without a repository and the future prospects are unclear.

Question 9

Global distribution of coal

Answer 9

n/a

Question 10

How efficient is Photosynthesis?

Answer 10

Solar Radiation (everything that hits the plants)
Theoretical yield 11%
Actual yield 3-6% it costs us nothing and it is converting it to energy that we can use and respiration for all living organisms that rely on it. Any percentage that we get is a bonus

Question 11

Advantages and disadvantages of renewable energy sources

Answer 11

Question 12

Advantages of intact forests(maintaining virgin forest land)

Answer 12

Biodiversity

Question 13
