Because you need a change of height to make the water run downhill and power a turbine. But of course you only get the power when there is a height difference, so the aim is usually to build a barrage across the mouth of an inlet and let it fill as the water rises, then you can let it out gradually over a period.
solar energy is energy from the sun and wind energy is energy from the wind
They are smaller in magnitude than those between lower energy levels.
Differences include mass; temperature; energy production; density; composition (percentage of elements).
Look at the equation for kinetic energy.It is clear that relation between mass and kinetic energy is linear (you would get a straight line on the graph), while the relation between speed and kinetic energy is quadratic (you would get a curve, specifically a parabola).
There are around 2,000 hydroelectric power stations in Britain. These power stations generate renewable energy by using the flow of water in rivers and streams to turn turbines and produce electricity.
They are smaller in magnitude than those between lower energy levels.
*Thermal
potential energy is stored energy. nuclear energy is radioactive
solar energy is energy from the sun and wind energy is energy from the wind

exothermic reaction releases energy and endergonic reaction absorbs energy
Fossil-fuel power stations, hydroelectric power stations and nuclear power stations.
Friction and cohesiveness are the only differences. The matter has stronger potential energy with stronger cohesive forces and the energy has stronger kinetic energy with demonstration as frictional force.
kinedice energy
An obvious answer is that the sources for the energy conversion is that the resources are renewable
