Can we say the Green Energy is a renewable energy?

I would say yes.

"Green energy" is renewable energy produced from sources that will not run out including:

Solar energy generated by the sun

Wind energy generated by wind

Hydropower generated by water

Geothermal energy generated by heat captured from the center of the Earth

Bioenergy generated from plants

yes, green enregy can be renewed.

Also referred to as green energy, renewable energy is generated from natural and renewable energy sources that can be replenished — as opposed to being generated by finite resources such as oil or coal. Different Examples of renewable energy include solar energy, wind energy, water power (hydroelectricity) and biomass. We call these green energy sources types of "renewable energy" because, unlike fossil fuels, such as coal and oil, green energy sources will not run out.

Yes . I agree MR ALEX and MR AMR

Renewable energy technologies are essential contributors to sustainable energy as they generally contribute to world energy security, reducing dependence onfossil fuel resources,and providing opportunities for mitigating greenhouse gases.The International Energy Agency states that:

Conceptually, one can define three generations of renewables technologies, reaching back more than100 years .

First-generation technologies emerged from the industrial revolution at the end of the19th century and include hydropower, biomass combustion andgeothermal power and heat. Some of these technologies are still in widespread use.

Second-generation technologies include solar heating and cooling, wind power, modern forms of bioenergy and solar photovoltaics. These are now entering markets as a result of research, development and demonstration (RD&D) investments since the1980s. The initial investment was prompted byenergy security concerns linked to the oil crises of the1970s but the continuing appeal of these renewables is due, at least in part, to environmental benefits. Many of the technologies reflect significant advancements in materials.

Third-generation technologies are still under development and include advanced biomass gasification, biorefinery technologies, concentrating solar thermal power, hot dry rock geothermal energy and ocean energy. Advances in nanotechnology may also play a major role

Yes, it's renewable as it is produced from renewable resources like waves, wind, sunlight, plants, geothermal heat . These resources naturally replenished as compared to fossil fuels which take extensive time millions of year to develop and will continue to diminish due to regular extensive usage.
