Which energy source can extract the energy without a sound?
Solar cells require very little maintenance, and they last a long time.
Which energy source uses blades to make energy?
Energy from the wind is produced by the kinetic energy of the blades when it spins. If there is too much wind, there is a brake to stop the blades. On the other hand, if there is no wind or not enough wind, there is a gear transmission box that can increase the blade speed. The bad part of the blade is that it could kill birds if they fly close to it.
Which energy source was used to turn a wheel?
Today, moving water can also be used to make electricity. Water power supplies about 10 percent of the entire electricity that we use.
Which energy source uses the sun or other stars to get all it's energy?
Plants use the sun’s light to make food. Animals eat plants for food. Decaying plants hundreds of millions of years ago produced coal, oil and natural gas that we use today. So, fossil fuels is actually sunlight stored millions and millions of years ago.
Which energy source is a fossil fuel made from animal remains?
. They were formed from prehistoric plants and animals that lived hundreds of millions of years ago. Coal formed from the dead remains of trees, ferns and other plants that lived 300 to 400 million years ago. In some areas, such as portions of what-is-now the eastern United States, coal was formed from swamps covered by sea water
Which energy source's dams, reservoirs, and generator's have environmental have impacts?
A dam to create a reservoir may obstruct migration of fish to their upstream spawning areas.A reservoir and operation of the dam can also change the natural water temperatures, chemistry, flow characteristics, and silt loads, all of which can lead to significant changes in the ecology
Which energy source do we use to fuel our airplanes, cars, and trucks, to heat our homes, and to make products like medicines and plastics
It also makes Ink, Crayon’s, Dishwashing liquids, Deodorant, Eyeglasses, CDs and DVD, Tires, Ammonia, and Heart valves. It was also produced in an oil refinery.
Which energy source has traces of impurities like sulfur and nitrogen?
When coal burns, these impurities are released into the air. Some of the tiny particles also get caught up in the swirling combustion gases and, along with water vapor, form the smoke that comes out of a coal plant’s smokestack.
Which energy source doesn't directly produce emissions of air pollutants and it is clean?
Which energy source can make solar water and electricity?
Which energy source gives of many emissions in the air likCarbon dioxide (CO2), Carbon monoxide (CO), and Sulfur dioxide e
It also gives off Nitrogen oxides (NOX), Volatile Organic Compounds (VOC), Particulate matter (PM), and Lead and various air toxics such as benzene, formaldehyde, acetaldehyde, and 1,3-butadiene
Which energy source in the last 20 years, scientists have developed ways to capture the pollutants that come from it?
Today, we have technology that can filter out 99% of the tiny particles and remove more than 95% of the acid rain pollutants in coal.
Which energy source is a fossil fuel made up of animal remains that contains oil, water, and gas?
Natural gas is found deep in the ground which comes from animal remains. Because animals contain oil and water as well, they have to remove them.
Which energy source was used as medicine for the Egyptions
Native Americans used oil as medicine and to make canoes water-proof. During the Revolutionary War, Native Americans taught George Washington's troops how to treat frostbite with oil.
Which energy source can be affected if clouds and pollution are in the air?
This is the disadvantage of solar energy.
Which energy source's energy is determined by the flow of water?
Swiftly flowing water in a big river carries a great deal of energy in its flow. Water descending rapidly from a very high point also has lots of energy in its flow. In either instance, the water flows through a pipe, or penstock, then pushes against and turns blades in a turbine to spin a generator to produce electricity
Which energy source was made stinky in case of a leak in the pipelines?
Natural gas is made up of a gas called methane. Natural gas itself isn't so smelly but they added stinky things to make a leak in the pipelines more noticeable.
Which energy source is made up of a flammable gas called methane?
Natural gas is a light, flammable type of gas which mostly contains methane. The energy is created by a steam turbine and a gas turbine which extracts the energy to create electricity.
Which energy source was formed from the remains of animals and plants (diatoms) that lived millions of years ago in a marine environment before the dinosaurs?
. Over millions of years, the remains of these animals and plants were covered by layers of sand and silt. Heat and pressure from these layers helped the remains turn into what we today call crude oil.
Which renewable energy source needs constant wind?
The bad part about wind energy is that it needs constant wind. Even if there is no wind, it has a gear transmission box that can spin the blade. However, the gear transmission box does not produce enough electricity.
Which energy source was used for heating, and stove and cooking?
James watt used coal to make the steam to run his engine for machines. In 1875, coke (which is made from coal) replaced charcoal to make steel. In the1880s, coal was first used to generate electricity for home and factories by burning.
Which energy source is bad for nature because of its noise?
Wind is not so good for the nature because of its noise. It can also kill innocent birds with its blades. Another problem is that to create the wind turbine, it requires a lot of electricity. However, the worst case scenario is if the oil leaks causing the wind turbine to burn down. Fortunately, this is rare and it does not occur that often.
