Fossil Fuel-Based Energy

Fossil fuels provide for 80% of the world's current main energy consumption, and the energy system is responsible for around 2/3 of all CO2 emissions. Given that emissions of methane and other SLCPs are thought to be greatly understated, it is probable that an even bigger portion of emissions are produced through the use of energy. In addition, several biomass fuels are presently used on a small-scale basis for cooking and heating around the world. Particularly for indoor air quality in many developing nations, these are incredibly inefficient and harmful. It is problematic for sustainable development to use renewable biomass in this manner. Emissions will significantly exceed the amount of carbon that can be emitted if the increase in the average global temperature is kept to 2°C by 2050 if current trends continue, or if the current share of fossil fuels is maintained and energy demand nearly doubles by that time. For the planet's climate, those emissions would be catastrophic. There are many opportunities for the energy sector to reduce emissions. Notably, switching to cleaner fuels and exercising more control over CO2 emissions can both reduce energy consumption and the net carbon intensity of the industry.
