There are lots of potential energy sources; some of them include solar energy, wind energy, nuclear energy, and many others more.
Oil shale and tar sands
Solar and wind renewable energy, of course. Oil shale and tar sands
Renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass, biofuel and hydrogen).
As petroleum supplies dwindle, renewable energy resources such as solar, wind, and hydroelectric power could play a significant role in replacing fossil fuels. Additionally, advancements in battery technology and energy storage solutions may enhance the viability of electric vehicles and grid systems. Alternative fuels, such as biofuels, hydrogen, and synthetic fuels, also present potential substitutes for petroleum in various sectors. Together, these resources could contribute to a more sustainable and resilient energy future.
I didn't know we had one...
Solar power is the obvious choice. A recent study showed that electricity from photovoltaic (PV) sources (roof panels) was something like 30 times more efficient than biofuel. (Photosynthesis captures 1% of solar energy; photovoltaic panels capture 10% and this figure gets better all the time.) Source link below.
In 2009, the US had an average petroleum consumption of 18,686,000 barrels per day.
Texas is the number one petroleum producing state.
It is like saying have a good day, only people replace day with one. It is a saying. Have a good one.
No one invented petroleum, it is a naturally occurring substance.
Petroleum Reservoir
Petroleum is one of Cameroons natural resources because there is an abundance of it.
