Good things/bad things about renewable energy and non-renewable energy can anyone name me some good things/bad things about renewable energy and non renewable energy source(s): good bad renewable energy renewable energy: . What is coal 9 february 2015 most people know coal as a fossil fuel which is used to produce around 40 percent of the world's electricity 1 it’s a flammable black or brown sedimentary rock, and is made mostly of organic carbon. Fuel cells can be used in cars, and to provide electricity to rural areas with no power lines to power a car, the electricity produced from hydrogen energy flows into the battery, acting much like today's hybrid electric cars. More information about why fcevs are good for california can be found on the california fuel cell partnership's website hydrogen production hydrogen can be produced from many domestic feed stocks, such as natural gas and renewable resources like water, using electrolysis while the most common method of making hydrogen, using natural.
For example, new gas-powered fuel cells are 40 percent to 80 percent efficient, with no combustion or emissions involved in the energy conversion process likewise, the next generation of hybrid-fuel cars will improve efficiency by capturing kinetic energy from the wheels to power the battery. Three good reasons to do nanotechnology: 1 for a sustainable energy economy for a sustainable energy economy when i was in norway a few months ago, i was talking to an official from their research council about the. Why is solar energy good source of energy these days solar energy is the most popular energy source in the world here is the list featuring the most important factors that make solar energy a „good energy source“. Hydrogen may prove fuel of the future will the most common molecule in the universe make for pollution-free cars.
Lactate physiology and sports training the body must use a third source of energy, carbohydrates or more precisely glycogen, to fuel the extended high intensity exercise that is crucial for good most athletic events carbohydrates are used both by the aerobic system to produce energy and by the third system, glycolysis or the. Learn more about hydrogen and fuel cells from the fuel cell technologies office hydrogen as an alternative fuel hydrogen is considered an alternative fuel under the energy policy act of 1992. Fuel cells can operate at higher efficiencies than combustion engines, and can convert the chemical energy in the fuel to electrical energy with efficiencies of up to 60% fuel cells have lower emissions than combustion engines hydrogen fuel cells emit only water, so there are no carbon dioxide emissions and no air pollutants that create smog. Primary energy sources take many forms, including nuclear energy, fossil energy-- like oil, coal and natural gas-- and renewable sources like wind, solar, geothermal and hydropower these primary sources are converted to electricity, a secondary energy source, which flows through power lines and other transmission infrastructure to your. Why solar powered energy is better than fossil fuels are fossil fuels our friend fossil fuel has been around for millions of years they have been used for powering countless things such as our household, businesses, manufacturing, and our cars to name a few our dependency has dated far back in time and continues even till today.
Replacing oil: alternative fuels and technologies download citation most experts look to alternative fuels and technologies as promising complements to petroleum in the near term and likely substitutes in the long term currently, 98 percent of the us transport sector runs on petroleum the reasons for this dominance are simple. Why alcohol fuel the two-minute summary the two-minute summary almost every country can become energy independent anywhere that has sunlight and land can produce alcohol from plants brazil, the fifth largest country in the world imports no oil, since half its cars run on alcohol fuel made from sugarcane, grown on 1% of its land. I’ve written my own debunking of the legitimacy of hydrogen fuel cell cars physicist joe romm, phd, who oversaw oversaw $1 billion in r&d, demonstration, and deployment of low-carbon technology in 1997 as acting assistant secretary of energy for energy efficiency and renewable energy under president bill clinton, has written several articles and an entire book on why. Hydrogen is a rich source of energy for many reasons the main being that it’s bountiful in supply while it may take a lot of resources to harness it, no other energy source is infinite as hydrogen that, essentially, means there is no possibility of it running out like other sources of energy. Why atp is always used as a energy source in almost all the living things.
Some hydrogen-powered vehicles fitted with hydrogen fuel cells have already been made and are on the road, but there are few of them because of difficulties involved in making and handling hydrogen. Advantages: can be produced with plentiful water, no direct co2 when produced with water, good subsitiute for water, high efficieny with fuel cells disadvantages: negative net energy yield, co2 if produced from carbon-containing compounds, high costs recquire subsidies, needs h2 storage and distribution system. As mentioned earlier, there are a number of other systems that must be included in the overall efficiency analysis of a fuel cell-powered vehicle-the electronic inverter, motor, air compressor (fuel cells needs oxygen that must come from the air) and the energy needed to get the hydrogen fuel stored in the tank of the vehicle these subsystems. Fossil fuels vs renewable energy resources by eric mclamb, september 6, 2011 energy’s future today the sun is the ultimate source of energy for our planet its energy is found in fossil fuels as well as all living things harnessing its energy holds great promise for the world’s energy needs, and it will be heavily called.
How cheap gas, weather & fuel cells are driving the consumerization of energy by rick nicholson, group vice president, idc energy insights jan 6, 2013 . The other main fraction is glucose, which can be used by all our cells for energy and is the main fuel for life on earth because glucose is the good sugar, can be used by all our cells for energy and is essential for some parts of our bodies, the best sources of natural carbohydrates are starchy vegetables starch is a complex polymer of. The argument against hydrogen fuel cells is not that they can't be a good alternative to fossil fuel cars or that they 'just don't work', but that there are many technological and even fundamental physical problems (ie the laws of nature are against us) that need to be solved to get there and you can prove that even if you get there.
