What is the advantage of using plants high in cellulose like sorghum and switch?
What is the advantage of using plants high in cellulose like sorghum and switch grass instead of corn? They can be grown in hot and dry environments. The biggest problem with using biofuels is scale.
Why is gasoline a miracle fuel?
#9 gasoline is described in the documentary as a “miracle” fuel. why is it so ideal for transportation? Gasoline is ideal for transportation because you can re-fill fast and there’s no “ash” or “residue” and has 4 times the density of liquid hydrogen. You just studied 24 terms!
What waste product’s are given off by geothermal plants switch?
Geothermal power plants do not burn fuel to generate electricity, but they may release small amounts of sulfur dioxide and carbon dioxide.
What advantage do biofuels have within our current system?
Plant-based fuels come from renewable sources, can be grown anywhere and have lower carbon emissions as compared to fossil fuels. Biofuels not only help a struggling economy by providing jobs but also helps in reducing greenhouse gases up to much extent by emitting less pollution.
What is the biggest hurdle in developing nuclear power the cost of the plant or the fuel?
Costs remain the biggest hurdle for the nuclear industry.
What advantage does wind power have over other renewable resources switch?
Wind is a renewable energy source. Overall, using wind to produce energy has fewer effects on the environment than many other energy sources. Wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling.
How is shale gas produced by hydraulic fracturing?
During hydraulic fracturing, a mixture of water, chemicals and sand is pumped down a borehole at high pressure. The water pressure opens up cracks in the rock and the sand grains lodge into the spaces to keep them open, allowing the released gas to flow out of the rocks and travel back up the borehole.
What is the single biggest problem with hydrofracking quizlet?
What is the single biggest problem of hydrofracking? Natural gas is very difficult to store.
Does geothermal pollute the air?
Geothermal energy can cause pollution if not managed properly but this is minimal. While small quantities of toxic gasses are sometimes released, greenhouse gases such as carbon dioxide (CO2) are the main emissions.
Why do geothermal power plants cause global warming?
When geothermal power plants do emit gases, it’s mostly carbon dioxide, which isn’t a pollutant but a greenhouse gas. Still, geothermal power plants emit much less carbon dioxide than fossil fuel power plants.
Does biofuel emit CO2?
When biofuels are burned, they emit roughly the same the amount of CO2 per unit of energy as petroleum fuels. Therefore, using biofuels instead of fossil fuels does not change how quickly CO2 flows into the climate bathtub.
Why is biodiesel not widely used?
“The feedstock inputs you need for biodiesel are more expensive than petroleum is,” Jones Prather said. “On top of that, the processes for producing the fuel aren’t yet efficient enough so that you can produce it very cheaply.”
