‘If our calculations are correct...’ generation and consumption of renewable energy are on the rise, climbing considerably between 2016 and 2017. In 2017, renewable energy sources generated about 17% of electricity in the U.S. Solar power alone provides a growing share of electricity in the country, with over 50 GW of installed capacity generating about 1.3% of the country's
I'm trying to see what percentage of total electricity demand will be met by solar power in some year x. Let's say I have data saying that the total electricity demand in country A is 1000 billion units (BU) in 2025.

Watts to GW conversion calculator How to convert gigawatts to watts. 1GW = 10 9 W = 1000000000 W. 1W = 10-9 GW = 1/1000000000 GW. Gigawatts to watts conversion formula. The power in watts P (W) is equal to 10 9 times the power in gigawatts P (GW):. P (W) = 10 9 × P (GW). Example
Although you may not have remembered the date, you’ve probably heard of Doc’s DeLorean, which takes 1.21 gigawatts (GW) of power to travel through time. Admittedly, our national labs haven’t quite figured out time travel just yet, but they do analyze power.
According to the automaker's website. (link is external) , the Nissan Leaf has an 110 kilowatt (kW) motor. So, 1 million kW divided by 110 kW = the maximum power of 9,090 Nissan Leafs.
In the above formula, we can see that the two components involved in the EER formula are Total Energy Expenditure and Energy Deposition.
EER (Estimated Energy Requirement) is the intake of diet required by an individual to maintain balance. This intake depends on certain factors including age, weight, gender and the level of physical activity a person is involved in. The use of a quality calculator is the best way to determine correct EER values.
The output will likely be in megawatts; a gigawatt is equal to 1,000 megawatts. A megawatt hour (MWh) is one megawatt of electricity produced for one hour. Determine the generator production capacity in megawatts and translate that to a power production figure in MWh. If your generator capacity is 10 megawatts, ...
Gigawatt hours per year (GWh/year) is a measure frequently used for electric generator output. To get the rate of electricity production for the year of your generator, you need to know the output capacity of the generator, whether it is a wind turbine, geothermal or other.
A gigawatt of power will provide enough energy for about 700,000 homes. Assumptions: A typical home uses about 11,000 kWh per year. A baseline 1 gigawatt power plant with an uptime of 88% (typical for coal plants) will provide 1 GW x 365 x 24 x 0.88 = 7,700 gWh of energy over the year.
Since a gigawatt is 1,000 Megawatts and a Megawatt is 1,000 Kilowatts, it would power quite a few homes. How many would be dependent on the lifestyles of those living there, the ambient temperature and how efficient their air conditioners and appliances were. For instance a family just getting home from work and school in the early fall when late summer's heat is at its peak would most likely turn their air conditioner on and it would likely stay on for a while to get the house cooled back down. An air conditioner, depending on capacity and efficiency might use 4-7 KW on average. Then they might throw a load of clothes In the washer, starting the water heater heating to recover as its stored hot water is used, typically 4,500 watts or 4.5KW. The washer motor itself will draw a few amps, probably around 0.5KW. Then they might start preheating The oven, another 3-4KW, then if they start heating some water for cooking potatoes and maybe start frying some chicken on the stovetop and maybe even some artichokes put on to steam, the surface burners might account for another 3-4KW. Someone starts the washer load in the dryer and another washer load so the washer and water heater are still running and the dryer adds another 5KW or better to the load. Then maybe sister heats up some water in the microwave for tea, brother heats up a toaster pastry in the toaster and mom puts on a pot of coffee, all around 1-1.5 KW each. Of course during this time lights of various wattages are being turned on all over the house, maybe another 2-3 KW if they're not conservative. Then dad gets home from work and plugs in his electric car to recharge, gets out the electric lawn mower, string trimmer, and leaf blower. Meanwhile sister #2 jumps into the shower to get ready for her date that evening helping to keep the water heater going and using up to 1.5KW for her hair dryer. This would be one extreme of power usage and the other would be at night when almost nothing is being used and very little electricity is needed. So as you can see the number of homes supplied would depend a lot on time of day and use habits.
The US Energy Information Administration says that in 2014, average US home electrical consumption was 911 kWh per month.
Based on the above assumptions, a gigawatt power generator (if attached to a constant load without peaks), should power about 725,000 homes. Incidentally, 1 Gigawatt is more power than produced by conventional power plants. 44% of power in the USA comes from coal.
Muckerman: If you're looking at -- 1 gigawatt could realistically power 300,000 homes. And while lightning strikes vary in strength, Dr. Brown was right: they can produce 1.21 gigawatts of power. That's a sobering fact when you consider that lightning is Utah's second deadliest natural hazard and has been for the last 15 years according to Utah.gov.
Nuclear power accounts for 34% of US power production. The output of nuclear plants in America range from 500MW to 4 GW. The Palo Verde nuclear power plant in Arizona is the largest with three reactors and a total capacity of just under 4 GW.
It’s an impossible question to answer, since Gigawatts is not a unit of energy, it’s a unit of power. Power, in this case, is energy per unit time. 1.21 GW means that energy is being supplied at a rate of 1.21GJ every second. That’s about the same energy (per second) as found in 26 gallons of gasoline.
The reason that kilowatts-hours are typically used as a measurement of energy rather than watt-hours is simply because of scale: the amount of energy a typical household in the United States uses in a year is on the order of millions of watts, ...
Kilowatt-hours (kWh) are a unit of energy. One kilowatt-hour is equal to the energy used to maintain one kilowatt of power for one hour. Generally, when discussing the cost of electricity, we talk in terms of energy. Energy (E) and power (P) are related to each other through time (t): P = E/t.
Watts (W) is a unit of power used to quantify the rate of energy transfer. It is defined as 1 joule per second. A kilowatt is a multiple of a watt. One kilowatt (kW) is equal to 1,000 watts. Both watts and kilowatts are SI units of power and are the most common units of power used. Kilowatt-hours (kWh) are a unit of energy. One kilowatt-hour is equal to the energy used to maintain one kilowatt of power for one hour. Generally, when discussing the cost of electricity, we talk in terms of energy. Energy (E) and power (P) are related to each other through time (t):
One of the most common units of electrical power for appliances is the watt (W). Other common units of power include kilowatts (kW), British thermal units (BTU), horsepower (hp), and tons.
It is used mainly in the United States to describe how well refrigerators and air conditioners extract heat. 1 ton ≈ 3517 watts.
BTU and BTU/h. British thermal units (BTU) are a measurement of heat used as part of the Imperial and US customary units of measurement. It is defined as the amount of heat that is required to increase the temperature of 1 pound of water by 1 degree Fahrenheit.
BTU/h, BTU per hour, is a unit of power that represents the energy transfer rate of BTU per hour. BTU/h is often abbreviated to just BTU to represent the power of appliances. For example, an AC marked with a label of 12,000 BTU actually has a power requirement of 12,000 BTU per hour.
