cons of fracking

-allows toxic chemicals and methane gas to seep into drinking water -unacceptable levels of radioactive Radium 226 is in the gas development waste jsmall scale earth quakes

following statements correctly explains the role of fossil fuels in the production of energy?

The combustion of fossil fuels heats water to produce steam, which then turns a turbine.

Which of the following best describes how the use of hydrogen fuel negatively impacts the environment?

The energy needed to produce the hydrogen fuel may come from fossil fuels, whose use contributes to ocean acidification and global climate change.

best describes the method of vehicle transport that is the most environmentally sustainable?

The use of a vehicle powered by hydrogen fuel cells because there are no carbon emissions

drawback to using biofuels, such as ethanol, as a fuel source?

There is high energy investment in producing and processing the crops needed for ethanol production.

what does sulfur dioxide help create

acid rain

what does coal produce

co2 and sulfur

what are biofuels

combustion of a fuel from something that was once living. This means it is a renewable fuel because we are able to regrow it.a

examples of biofuels

ethanol and biodiesel

solid biomass

manure

best describes an environmental problem associated with hydrologic fracturing, or fracking?

Fracking fluids can escape from the drill hole and contaminate surface water and groundwater.

hroughout the world, especially the less-developed countries, burning wood or other biomass for heating or cooking in homes is common. One negative environmental impact of this practice is the production of particulates indoors, which can be a health hazard to humans. how to help

Installing effective ventilation systems in dwellings B

Which of the following would be the best location for a wind farm with ten industrial turbines?

Arranged uniformly on a local farm that has fields and pastureland for dairy and grain production

advantage of burning biomass rather than burning fossil fuels in developing countries?

Biomass production is cheaper than fossil fuel extraction, making it more readily available for use.

Which of the following describes an environmental problem that can result from the combustion of fossil fuels to generate electricity?

Carbon dioxide is a product of the combustion fossil fuels, and it can lead to global climate change when released into the atmosphere.

n an apartment building, exhaust from a gas-powered electrical generator is captured to produce hot water to heat a swimming pool. Which of the following is illustrated by this process?

Cogeneration

characteristic of nonrenewable energy sources that distinguishes them from renewable energy sources?

Nonrenewable energy sources typically take a longer time to replenish than renewable energy sources do.

why are offshore wind farms better than on shore

Offshore winds farms will produce up to three times as much electricity as wind farms on land because of increased wind speeds offshore.

best supports the argument that nuclear energy is a nonrenewable energy source?

The uranium deposits on Earth are finite.

is the most practical solution to maximizing energy production at wind farms while minimizing the risk to wildlife?

Turn off turbines during periods of maximum migration. C

what is hydraulic fracking

is to obtain additional natural gas and petroleum from solid rock layers. Involves pumping "fracking fluid" first down into the earth and then horizontally through the layer of rock that contains natural gas and petroleum. The fluid shatters the rock open, releasing natural gas and petroleum that can be pumped up.

cons of natural gas

potent green house gas it is methane climate changer can lead to explosions

cons of oil

produces co2 must be refined oil leaks

what is nuclear powr

splitting of a large, unstable nucleus of an atom. This process releases tremendous amounts of energy.

uranium used for fuel

u 235

most common uranium

u 238

Geothermal energy plants are a viable alternative energy source because they

use the heat from Earth's interior to create steam that is used to generate electricity and then can be pumped back into the ground
