Biomass comes from plants which are results of photosynthesis powered by the sun. In essence, wind, biomass and hydropower are all secondary forms of solar energy (Timmons et al., 2014). Sign in to download full-size image Fig. 12. Classification of various renewable energy sources.Source: ...
"I would like to thank Chinese enterprises for investing in hydropower plants, a source of clean energy, in Cambodia," he said in a speech during the river closing ceremony for the construction of the hydropower station in Thmar Baing district. "Chinese-built hydropower plants have helped secur...
D Common water plants could provide a green energy source. Scientists have figured out how to get large amounts of oil from duckweed, one of nature's fastest-growing water plants. Transferring such plant oil into biodiesel(生物柴油) for transportation and heating could be a big part of a mo...

Scientists are exploring ways that they could be used as a power source for nearly exhaust-free automobiles and how they can be used as electricity-generating plants. The high cost of manufacturing fuel cells has prevented the mass use of this valuable energy source. I Ocean sources; Oceans, ...
The environmental burden of the United States’ bitcoin mining boom The paper maps air pollution from power plants supplying electricity to US Bitcoin mines. It finds that 1.9 million people in 2022-2023 breathed toxic amounts of Bitcoin mine attributable pollution, particularly around New York Cit...
Testing the feasibility of multi-modular design in an HTR-PM nuclear plant Small modular reactors are compact nuclear reactors that can be combined to create large-scale power plants. Here, authors demonstrate the practical feasibility of a multi-modular design in the HTR-PM nuclear plant, showing...
a renewable energy source as it does not replenish within the lifetime of a person[3]. At the turn of the century, renewable energy sources supplied ~14% of the total world energy demand[4]; by 2010, this had risen to almost 17% with an estimated 50% of energy demand by 2040[5]....
