90% does they get
In the US, 19 percent of total electricity. In the world, about 16 percent
Could be the total of coal and nuclear
In the US for 2006 electricity production, geothermal produced 0.30 percent. I do not have world figures
20 percent of the world's electricity and 6 percent of its total energy.
Total energy used/total energy produced
Plants constitute 90% of the Earth's total biomass.
In the United States, nuclear power accounts for about 20% of the total electricity generated. It is one of the largest sources of clean energy in the country, providing a reliable and low-carbon energy source.
GPP stands for Gross Primary Productivity in biology. It represents the total amount of energy that plants capture through photosynthesis. GPP is a measure of how much energy is produced by plants before accounting for the energy they use during respiration.
73 % is electrical energy
The total amount of energy produced by a system when the energy times time is calculated together is known as power. Power is the rate at which energy is transferred or converted.
The percent efficiency would be calculated by dividing the useful output by the total input energy and multiplying by 100. In this case, the useful output is 6W (light energy produced) and the total input is 60W (electricity consumed). Therefore, the efficiency would be (6/60) * 100 = 10%.
When energy changes forms, it is not always produced. In fact, energy is conserved in a system, meaning it can neither be created nor destroyed. So, when it changes forms, the total amount of energy remains constant.
