Biomass
Almost half of all renewable energy in the United States comes from hydropower. This is primarily due to the country's extensive network of rivers and dams, which harness the energy of flowing water to generate electricity. Additionally, hydropower has been a well-established energy source for over a century, contributing significantly to the overall renewable energy mix. Other sources like wind and solar are growing rapidly, but hydropower remains the largest contributor.
No, although we have more wind farms then anywhere else on the planet. Wind will never replace fossil fuels because they are extremely inefficient and fossil fuel plants are required to provide makeup for wind when the winds varies.
Hydropower is a commonly used renewable energy source in both the US and Canada. It involves harnessing the energy of flowing water to generate electricity through dams and hydroelectric power plants.

The source of electrical energy in a galvanic cell is the chemical reaction that takes place between the two half-cells. This reaction creates a flow of electrons from the oxidation half-reaction to the reduction half-reaction, generating an electric current. The movement of electrons through an external circuit is what produces the electrical energy.
Some are, and some aren't. Be10 and C14 for example are continuously created by hard radiation from space. Bi has a half life many times the age of the universe! Some radio nuclides are daughter products of other nuclides, so appear renewable.
There must be a source of sufficient light. Ie. Solar energy is only charging half the time on earth, as we spin and only face the sun half the time!
