In previous post, I shared brief overview about common renewable energy sources, such as solar power, wind power, and hydro power. In this post, I want to continue sharing about other renewable energy sources, which are geothermal, biomass, and energy sources from sea (wave, tidal, and ocean thermal energy conversion).
Geothermal Energy
Geothermal energy is renewable and offer more advantages than other renewable energy sources, such as hydro, wind, bio energy, biomass, and wave energy. It has high degree of availability, low land use, insignificant dependence on weather conditions, and comparatively low visual impact.
Global installed capacity of geothermal power has reached 14.4 GW, with the US as the largest geothermal country so far.
The vast majority of geothermal energy source are located closed to volcanic activity areas.
Biomass is one of alternative energy that can ease our dependence on fossil fuels. Biomass is renewable, it can be grown worldwide. There are many potential biomass sources, such as food crops, algae, trees, waste from cities and factories, and methane from landfills.
Biomass can be converted to thermal energy, liquid, solid, or gaseous fuels and other chemical products through various conversion processes.
In general, the most prominent bioenergy technologies are comprised of direct combustion, co-firing, gasification, pyrolysis, anaerobic digestion, and fermentation.
