1.21 gigawatts.
1.21 jigawatts. (That is not a real unit just so you are aware, people often mistake it for a gigawatt but it is actually jigawatts, so it is either just made up to sound cool or it is meant to be above the 1x10^15 named limit)
Because solar panels/ cells which collect the solar energy are expensive also they are very unreliable when the sun is not out. .Payback time is expensive .time consuming .It does not produce that much power which we need. . it does not produce energy in night. . The amount of energy obtained changes depending on the climate.
In the winter it's cold and you need energy to keep you warm and in the summer it's hot you don't need energy you let out energy when you sweat etc.
Not that much, it would help but The last 3 took place in "The Past" when Salvation is during the future war (2018)
Eight days pass in the first one. Marty departs from and arrives back to the date October 26, 1985. He arrives in the past on November 5, 1955, and departs from the past on November 12, 1955. So, he spent one week in the past. We also followed him around the entire day of October 26, 1985: from the morning of October 26 when he's late for school again, until he goes back in time. Then, after spending a week in the past, he returns to October 26, 1985, ten minutes earlier than the time he departed from. And the next morning -- October 27 -- he and Jennifer go into the future with Doc Brown. So, the whole movie takes place over the course of eight days: seven days in the past, and one day in the present.
Wind energy is ONE energy of the future. But due to its random accessibility (sometimes it's not blowing) we'd need other energy sources as well to fill the gaps.
In none of the back to the future movies have they ever created nuclear power. In the first one they used lighting to generate 1.21 gw of energy, and then the professer fixed it in the beggining of the second movie so you don't need nuclear power to go back.
It will have to, in the long term; by definition, the alternatives are not sustainable. People have lived for thousands of years with renewable energy sources; we will somehow have to do this again in the future... or else.
Need answer now.....so that i can finish essay
A calorie is a measure of energy. It doesn't make sense to ask how much energy you need to lose energy.
Baby's need a lot of energy (90%)
Other sources of energy that will not run out are tidal energy, from the rise and fall of Earth's ocean.
Half as much as you need to get back.
If you go back to him then you are indicating to him that his dumping you was OK. In the future, he will probably take this as permission to do it again. You need to decide how much you are worth to yourself before you allow someone back in to your life who has hurt you in the past.
That follows directly from the definition of "renewable energy". A renewable energy is simply one that can be sustained in the long term.
Because they dont use their energy that much
lots for the dancer because they need energy drinks to keep them going.
