Coal - about 50 percent of total
The Sun isn't our primary source of energy. The world still relies on burning fossil fuels as a main source of energy. Solar power only provides one percent of the world's electricity production.
Glucose (and CO2)
Electricity and after that natural gas.
electricity, geothermal, nuclear, and probably more
The main source of energy that powers the sphere is electricity. This electricity can be generated from various sources such as fossil fuels, nuclear power, renewable energy sources like solar and wind, or even from batteries. The specific source of electricity depends on the location and infrastructure of the sphere.
For electricity it is still coal, for transport it is oil
Oil is the main source of electricity worldwide.
coal is the main source of electricity in Germany
Sunlight is the main source of energy on earth
The nuclear fission on the sun is the main source for solar energy. This radiation strikes the earth where it is captured by photovoltaic (PV) panels, or focussed on a Solar Tower. Both methods produce electricity, which is clean and renewable.
Nuclear fission is main source of solar energy,
well its obvious isn't it ? its used to generate energy and produce fuel
