Which example is NOT a renewable resource?
Trees
Wind
Solar
Uranium (Nuclear)
What is one disadvantage of coal?
Coal produces air pollution.
There isn't a lot of coal left which makes it expensive.
The world isn't using a lot of coal which makes it an undesirable job.
You can only use it to roast hot dogs and cook hamburgers.
All are examples of Nonrenewable energy sources EXCEPT...
Coal
Petroleum
Hydropower
Uranium (Nuclear)
What is one disadvantage of renewable energy?
Electricity and power could become much cheaper.
Third world countries could have affordable energy.
Many people could become energy independent.
Most sources are expensive to get started.
How is geothermal energy harvested? (How do we get it?)
solar panels collect the sunlight.
The heat from the earth boils water to create steam.
We pump it from the earth and refine it into gasoline.
We drill for it and burn it like coal or wood.
What is one disadvantage of using hydropower?
Hydropower is a renewable energy resource. There are no disadvantages.
The power is used as electricity to power large buildings instead of homes.
Building dams can damage natural wildlife and water systems like lakes and rivers.
Most of the time there isn't enough water power to create electricity.
Over the years, oil and gas companies have made us believe we are running out of oil. What could be one reason why they are telling us this?
To make us use less gas in our cars
So car companies will make electric cars.
In order to tell us they are going out of business soon.
So government will allow them to drill in more areas.
.Which of these is an example of biomass energy?
A coal-burning generator
A wood-burning stove
A gasoline-burning automobile
An automobile that operates on fuel cells
How is natural gas different from coal?
Natural gas is a renewable resource; coal is a fossil fuel.
Natural gas is a form of petroleum; coal is extracted from coal deposits.
Coal is a form of petroleum; natural gas is emitted by volcanoes.
Coal is a fossil fuel; natural gas is a renewable resource
Which of these is an advantage of fossil fuels?
You can extract them without complicated machinery.
They are relatively inexpensive to produce.
Burning them does not have any negative side effects.
There is an unlimited supply of them.
____________ is produced through methods that do not release greenhouse gases or any other pollutants

a wind farm can easily be built in locations away from birds
a wind farm produces enough sound to keep birds away
a wind farm produces a greater amount of electricity than a single wind turbine produces
Why is nuclear energy considered nonrenewable?
some people do not support the use of nuclear energy as a resources
