What energy challenges is the world facing now?

Summary. The world lacks safe, low-carbon, and cheap large-scale energy alternatives to fossil fuels. Until we scale up those alternatives the world will continue to face the two energy problems of today. The energy problem that receives most attention is the link between energy access and greenhouse gas emissions.

Fossil fuels can get depleted with use. The problem of environmental damage that come with the use of fossil fuels includes global warming, acid rains, dangers posed by leaded fuels, oil spills, gas leaks and explosions, water pollution caused by poorly managed coal mines and Air pollution.

How does energy affect the environment?

The environmental problems directly related to energy production and consumption include air pollution, climate change, water pollution, thermal pollution, and solid waste disposal. … The emission of air pollutants from fossil fuel combustion is the major cause of urban air pollution.
