Thermal processes like combustion, used in fossil fuel power generation and conventional cars, have inherent inefficiencies due to physics (e.g. Carnot cycle) which can be avoided through renewable energy processes.
Thermal mga proseso tulad ng pagkasunog, na ginagamit sa fossil fuel power generation at maginoo kotse, mayroon likas inefficiencies dahil sa pisika (eg Carnot ikot) na maaaring naiwasan sa pamamagitan ng Renewable enerhiya proseso.
