They do, but if you are asking why it is not done on a larger scale, it has to do with money. For the current energy companies to switch over to a new technology cost money upfront. This will cut into the business's short term profits, and in big business (which is who owns the energy sectors) the short term profits are valued higher than long term.
Because renewable energy use does not make for good consumers.
We are still dependent on fossil fuels due to factors such as the intermittency of renewable sources like solar and wind energy, limitations in energy storage technology, and the high cost of transitioning existing infrastructure to renewable sources. Additionally, some regions may lack the necessary resources or infrastructure to fully utilize renewable energy at present.
Yes because nonrenewable energy can run out and you can use renewable energy for a long time
They are sometimes called alternative energy sourcesbecause they are not the ones used now. (Yet!)
As of now, no spacecraft are launched with renewable energy all use petrolieum. Many satalittes use solar however to provide electrical power when in orbit
It is renewable because you can always raise an object or raise yourself and gain gravitational potential energy. You cannot run out of gravitational potential energy and even now you have some of the the energy because gravity is always pulling you. It is just a matter of how much gravitational potential energy you have. Go on the top Mt. Everest and you will have more gravitational potential energy than most of the people in the world.

If you are talking about a normal light bulb no, the energy has been used and is now useless
yaHydroelectric energy is renewable rather than exhaustible, because water can be depleted.
Renewable energy sources like solar and wind are becoming increasingly competitive with fossil fuels in terms of price. In many cases, renewable energy is now cheaper than fossil fuels, making it a more cost-effective option for generating electricity.
i dont now
