Some alternatives to batteries for powering electronic devices include solar power, kinetic energy, fuel cells, and wireless power transfer technologies.
Many green alternatives to today's power plants exist but have not been perfected. Some of the most popular forms include Geothermal energy, solar power, and wind power.
The alternatives to burning coal for electricity generation are:Water (hydro power) if availablenuclear energybiomass and geothermal energyrenewable energy sources as solar and wind energy.
solar
there are many alternates to coal like wind power, solar power, geothermal, and there are other fossil flue alternatives like gas or propane.
solar energy
Renewable energy sources, such as solar, wind, hydro, and geothermal energy, will not run out because they are naturally replenished. These sources are sustainable and environmentally friendly alternatives to fossil fuels.
Some alternatives to fossil fuels for energy include renewable sources such as solar, wind, hydroelectric, and geothermal power. Other options include nuclear power and bioenergy from sources like biomass and biofuels. Transitioning to these cleaner energy sources can help reduce greenhouse gas emissions and combat climate change.
Solar Flux or Solar irradiance would be a couple of alternatives.
