The exact volume of diesel is dependent on temperature and exact density. Assuming the weight of 1-liter (L) of diesel equals to be .84-kilograms (kg) gives a yield of 297,619,047-L. 25000-metric tons equals 250000000-kg. Dividing how many kilograms into .84 kg/L yields the answer.
Hydro energy is using the power of water to run a machine. It was invented thousands of years ago when millers used the power of a stream to turn a paddle wheel to grind their corn into flour. The Romans and Greeks used hydro power around 200 BC.The use of hydro energy to produce electricity is much more modern. About 1870 a miner connected a dynamo to a water wheel to generate electricity.See the related question below.
