How does alternative fuel help the environment?
In theory, using biofuels can cut down your car's greenhouse gas emissions because burning them releases only the carbon that was absorbed when they were growing. That means releasing less CO2 into the air than the millions of years of carbon stored in the oil that powers most modern cars.
What are the advantages of fossil fuels?
Advantages:Fossil fuels can generate a large amount of electricity at a single location.They can be found very easily.They are cost-effective.Transportation of oil and gas can be done easily through pipelines.They have become safer over time.Despite being a finite resource, it is available in plenty.
What Are the Advantages of Alternative Energy?
1. They are a renewable resource. Sunlight is plentiful. Wind will happen. Sustainable crops can be grown. Gravity will always cause water to fall. The Earth will always generate its own heat. That means we don’t have to worry about our source of energy being fully consumed.
What Are the Disadvantages of Alternative Energy?
1. They can be regionally specific. You must be near a river to collect hydropower. You must live in a windy area to collect wind power. You must receive sunny days on a regular basis to collect some forms of solar power. This means alternative energy is regionally specific, with some being unsuitable.
Answer
C is the correct answer. A & B can be cancelled out, due to the fact that they are both pro-fossil fuel.
Answer
C is the most correct. However many alternative energy methods do not reduce the impact of fossil fuel burning, they just don't contribute.

2. What energy goes into Photosynthesis and what energy comes out? How does this show that energy is neither created nor destroyed? PLEASE ANSWER ALL …
What is alternative energy?
Alternative energy is defined as a resource that we use outside of what is possible from fossil fuels. That means items like wind, biomass, solar, and geothermal all qualify for this title. Hydropower is another option that fits into this category even though some producers need fossil fuels as a foundation to produce energy for consumption.
What are the disadvantages of alternative energy?
One of the primary disadvantages of alternative energy is that it is only available when the providing resource is present in the environment. Solar power only works when the sun is shining. Wind power is possible if there is air movement.
What energy do we use from the sun?
If the sun continues to shine, then we have access to solar energy. The warmth from the sun’s rays helps to create wind energy that we use. As long as our planet has water, then we can use tidal collectors and hydroelectricity structures. The existence of our world allows for geothermal energy.
Why is wind energy bad?
Wind energy can be problematic because bats and birds can fly into the turbines as they spin. Solar energy sometimes requires mercury in the creation of the panels that collect sunshine or thermal resources. These adverse impacts aren’t always considered even when calling these approaches “environmentally friendly.”
Why do we use fertilizer?
We use more fertilizers when producing alternative energy items . The amount of fertilizer used to produce alternative energy products continues to grow. Over 15 million metric tons of it is necessary to create enough algae to meet today’s bio-diesel demands. Another 2 million metric tons of phosphorus is also required.
Which is better, solar or geothermal?
Solar and hydroelectric energy offer this benefit to a lesser extent. Geothermal energy is often considered the best option since you can access it at any time once installed without worrying about emissions.
What are the different types of wind energy?
There are several different types of wind energy that we can produce today. Some of the most common options are offshore, utility-scale, and distributed . The placement of the turbines to collect this resource can make construction costs up to 50% more expensive than nuclear energy.
Why are wind turbines less prone to failure?
Distributed systems are spread out over a large geographical area, so a severe weather event in one location will not cut off power to an entire region. Modular systems are composed of numerous individual wind turbines or solar arrays. Even if some of the equipment in the system is damaged, the rest can typically continue to operate.
How does coal affect the environment?
The air and water pollution emitted by coal and natural gas plants is linked with breathing problems , neurological damage, heart attacks, cancer, premature death, and a host of other serious problems. The pollution affects everyone: one Harvard University study estimated the life cycle costs and public health effects of coal to be an estimated $74.6 billion every year. That’s equivalent to 4.36 cents per kilowatt-hour of electricity produced—about one-third of the average electricity rate for a typical US home [ 6 ].
What is CO2E in energy?
To make comparisons easier, we use a carbon dioxide equivalent, or CO2e—the amount of carbon dioxide required to produce an equivalent amount of warming. In contrast, most renewable energy sources produce little to no global warming emissions. Even when including “life cycle” emissions of clean energy ...
What are the effects of human activity on the atmosphere?
Human activity is overloading our atmosphere with carbon dioxide and other global warming emissions. These gases act like a blanket, trapping heat. The result is a web of significant and harmful impacts, from stronger, more frequent storms, to drought, sea level rise, and extinction.
Does fossil fuel price fluctuate?
In contrast, fossil fuel prices can vary dramatically and are prone to substantial price swings. For example, there was a rapid increase in US coal prices due to rising global demand before 2008, then a rapid fall after 2008 when global demands declined [ 23 ]. Likewise, natural gas prices have fluctuated greatly since 2000 [ 25 ].
Does biomass produce electricity?
Renewable electricity generation from biomass can have a wide range of global warm ing emissions depending on the resource and whether or not it is sustainably sourced and harvested.
Why do renewables require subsidies?
5. Renewables often require subsidies to make them affordable. In the United States, an emphasis on biofuels and renewable energies led to the creation of ethanol as a crude oil replacement. Despite taxpayer-funded subsidies in place for this corn-based fuel, only 430,000 barrels per day were produced in 2007.
Why are fossil fuels considered finite resources?
Fossil fuels, in theory, are a finite resource because of how they are created. 2. Multiple forms of renewable energy exist. Diversification within the renewable energy sector has exploded since the 1970s.
Do renewable resources require fossil fuels?
The technologies and facilities that are used to build renewable energy resources require fossil fuels, as do the transportation and distribution networks. In many instances, renewable energy relies on fossil fuels, whereas fossil fuels do not rely on renewables. 5.
