Sources of Energy

Fossil Fuels Continue to Dominate

Although renewables are the fastest growing world energy source, the planet still uses fossil fuels to meet the majority of its energy needs. Fossil fuels are projected to continue to supply much of the energy used worldwide through the year 2035, especially in emerging economies.

Ensuring Environmentally Safe Shale Gas Production

The recent boom in shale gas is expected to make up an increasing share of U.S. gas production, nearly doubling in volume over the next 25 years. Approximately 30% of this is expected to come from the Marcellus Shale field located partially in Pennsylvania. Although shale gas is a promising new source of low-carbon energy, concerns over methane release and groundwater quality persist.

How CMU is Addressing the Challenge

Expanding the mix of energy sources in a way that is clean, reliable, affordable and sustainable is a complex challenge that requires integrated solutions. Carnegie Mellon professors are developing technologies and policies that can help broaden the mix, while managing carbon emissions and ensuring that new forms of fuel such as shale gas are extracted responsibly.
