Is hydrogen already being used as a fuel? Yes. There are alreadycarsthat run on hydrogen fuel cells. China has the highest number of hydrogen fuelling stations for road vehicles worldwide, where you can fill up just as you would with petrol or diesel and in the same time frame as a tr...
Obviously, the total amount of energy remains the same, and energy cannot be lost or generated. This is the principle of energy conservation in an isolated system.Answer and Explanation: In the SI unit system, Joule (J) is considered as the largest unit of energy. 1 Joule is the amount ...
Data show that the installed capacity of renewable energy has surpassed one billion kilowatts, accounting for 44.8 percent of China's overall installed capacity. The installed capacity of hydropower, wind power, and photovoltaic power each exceeded 300 million kilowatts, all ranking the highest in t...
