How does biomass reduce our carbon footprint by producing less CO2 than fossil fuels?

• Plants absorb the same amount of CO2 that is released when it is burned.

• Plants remove CO2 from the atmosphere and put it permanently into the ground.

• Biomass filters CO2 to make it more environmentally stable.

• Biomass doesn't release any CO2 when burned.

Which of the following energy sources has the lowest negative environmental impacts?

• Biomass

• Nuclear

• Natural Gas

• Solar

Which of the following DOES NOT use a turbine?

• Hydroelectric

• Wind

• Solar

• Nuclear

Heating and cooling buildings by exchange with shallow groundwater systems is considered a form of ___ energy.  

• geothermal

• solar

• kinetic

• potential

What is and example of cogeneration?

• heat energy normally wasted is used to power a turbine

• a power plant that gets energy from both nuclear and hydroelectric

• a type of wind turbine that can be powered by wind or steam

• harvesting natural gas and petroleum from the same field

Put the items below in correct sequence for the generation of electricity using the wind
1 – generator converts mechanical energy into electrical energy
2 – wind turns the wind turbine blade
3 – the gear box transfers mechanical energy to the generator
4 – electricity is transferred to the grid

• 1-2-3-4

• 2-1-3-4

• 2-3-1-4

• 2-4-3-1

Most of the developing countries in the world depend on _______ for their main source of energy.

• renewable sources

• nuclear

• biomass (including wood, manure, etc)

• coal

a downside to relying on biomass as a primary fuel source for a nation is that

• it can cause soil erosion, water pollution, and habitat loss

• it requires little land use

• it produces no pollution

• it produces more pollution than coal 

The most commonly used approach to solar energy collection is ________, in which buildings are designed and building materials chosen to maximize their direct absorption of sunlight in winter, even as they keep the interior cool in the heat of summer.

• Active

• Passive

Which of the following is a disadvantage of solar energy?

• It can only be used effectively in certain regions and certain times of day

• It produces greenhouse gases during use

• It is a nonrenewable energy source

• It is inexpensive compared to other sources
