Yes magnets get weaker over time.
Rivers can be used to produce energy primarily through hydropower, which harnesses the kinetic energy of flowing water. By constructing dams or run-of-the-river systems, the movement of water is directed to turbines that convert the energy into electricity. Additionally, small-scale hydroelectric systems can be implemented in suitable locations to generate power without the need for large dams, utilizing the natural flow of the river. This renewable energy source contributes to reducing reliance on fossil fuels and lowering greenhouse gas emissions.
sustainable energy is the kind of energy that will never run out. example: solar energy, wind energy,etc.
The energy to run them is FREE!!!
It means it will never run out
Currently, the world is heavily dependent on fossil fuel. But we might soon run out of it, and the amount of pollution it is creating is also alarming. The future of energy sources lie in the non-conventional sources of energy, most importantly solar, wind and tidal energy. Also alternative forms of energy like Hydrogen and BioAlcohol based fuels are close short term alternatives to reduce the dependency on fossil fuel. They produce little or no carbon di oxide, and are cheaper to generate too.
Magnets never run out of energy.

if they get Zapped by a certain voltage they can
Yes, magnets can lose their magnetism over time due to factors such as exposure to heat, physical damage, or demagnetizing fields.
YES
It can be run through a resistor to produce heat, as in a convector heater, tumble dryer, toaster. It can be used to run electric lights, and it can be used to drive electric motors that produce mechanical energy.
When two objects run together to produce friction, heat is also produced as a result of the energy transformation from kinetic energy to thermal energy.
A dishwasher doesn't produce energy; it consumes energy to heat water, run the motor, and operate the controls.
The sun will eventually run out hydrogen at its core, which is the source of energy, so it will die, but it will not explode.
geothermal energy is a renewable source, so it will never ever run out.
In the short run, a lemon. For the carbs, and in the long run, a potato.
Disadvantages: May not produce enough energy to run appliances, solar radiation
