What are the main new energy sources currently being developed and utilized?
2 Answers
Currently, humanity is developing various new energy sources including solar energy, biomass energy, hydro energy, wind energy, geothermal energy, wave energy, ocean current energy, tidal energy, and thermal cycles between the ocean surface and deep layers. Additional information: Ocean energy: Ocean energy refers to various renewable energy sources contained in seawater, including tidal energy, wave energy, ocean current energy, ocean thermal energy, and salinity gradient energy. These energy sources share the advantages of being renewable and environmentally friendly, representing a strategically significant new energy source urgently needing development and utilization. Wind energy: Wind energy is formed by the flow of solar radiation. Compared to other energy sources, wind energy has distinct advantages—it is abundant (ten times that of hydro energy), widely distributed, inexhaustible, and particularly important for islands and remote areas with inconvenient transportation and far from main power grids.
I've personally seen many places using different new energy sources. Solar energy is the most widespread; my residential community has photovoltaic panels installed on the rooftops, generating electricity for lighting. Wind energy is also common, with those big wind turbines spinning in the suburbs. Hydropower mainly comes from hydroelectric power stations, where dams store water to generate electricity. Geothermal energy is widely developed in hot spring areas, extracting underground heat for heating. Biomass energy uses crop residues from rural areas to make fuel. Hydrogen energy is the new favorite, with cars like the Toyota Mirai utilizing it. Tidal energy is also being piloted in coastal areas. These energy sources are all renewable and reduce pollution, but storage technology still needs improvement, like making batteries more durable. Development is in full swing, with strong national support, and the hope is that costs will come down in the future, benefiting more ordinary people.
