A radical energy transition is underway, driven by a combination of environmental, political and technological factors. We are seeing a global shift from the use of fossil fuels, like oil and coal, to low carbon energy sources, like wind, solar and lithium-ion batteries. Greenhouse gas (GHG) emissions produced in the extraction and combustion of hydro-carbon fuel sources are one of the primary causes of climate change. The effects of the shift will be far-reaching and transformational.
The Paris Agreement of 2015, with its ground-breaking commitment to limit GHG emissions to levels consistent with global warming of between 2 °C and 1.5 °C by mid-century, is a useful starting point for thinking about the features of the energy transition. With an increasing population and greater energy needs, the challenge to reduce emissions will be enormous.
So far, consumption of renewable energy has not increased fast enough, and the electrification of power is just getting started. It will take decades to shift away from fossil fuels to lower carbon energy sources and implies efforts on many fronts. A fair chance of achieving net zero goals requires continued policy and legislative changes, shifts in investor and consumer preferences and, importantly, technological advances across industries.
