Towards the end of the 20th century, the evidence of the continued use of Fossil Fuels on the environment of Earth became harder and harder to ignore and dismiss. Not to mention, the realisation that supplies were limited, and at the current rate of consumption, society would run out within the next two hundred years - or less. 

The need to change something fundamentally was realised, and in the early 21st century, one of the only things that world powers agreed on was to meet and discuss the issue, and share research and debate ideas about alternatives. 
While the conference did not yield any obvious and immediate results, it did point to the understanding of all involved that change was necessary if human civilization was to continue in its' current form. 
Resolutions were signed by many allied global powers to devote considerable wealth and energy toward alternative energy sources of all kinds, and to reduce global emissions and pollution drastically. 

It wasn't until after the Heavenfall that this really came into effect. With the destruction of so much infrastructure, there was a need for rebuilding. Much of the mechanisms that supported the oil industry were centered around oceans and coastlines, or concerned with pipelines that stretched over vast distances, and were easily disabled or destroyed by the destruction. 
Green power became the standard very quickly afterward as a result. Wind, Tidal and Solar power generation were embraced en masse, providing the bulk of power generation worldwide. 
Other avenues were followed similarly and invested into heavily. Power generated from biofuels and recycling waste became much more common, and geothermal power likewise took off. 
In countries with less stringent regulations, fossil fuels still remained in use, and nuclear powerplants were rebuilt, or built anew. In countries more dedicated to environmental goals and the reduction of waste - including avoiding the production of nuclear waste, and the problems of its' long-term storage - nuclear power remained only for specialist purposes and roles. 
Hydrogen powerplants have been constructed and adopted as a backup or for use in areas where other solutions do not work, and hydrogen power and fuel cells are considered to be one of the next main breakthroughs in power generation and production, especially for vehicles and mobile applications. 

In urban areas, electric vehicles are starting to become a lot more commonplace where routes are shorter and reliable and constant access to a power grid is available for charging. 
For longer distances or in applications where electrical power for vehicles would not work, alternatives such as biofuels have been implemented, especially as they require minimal alteration to the vehicle using them. 

Fusion power still remains the ultimate holy grail of power, and is seemingly eternally 'just around the corner'. Many agencies, companies and other organizations world wide pour millions of dollars and just as much time into unlocking the secrets of fusion power, and there have been many close calls, but as yet no reported and confirmed successful self-sustaining fusion reactor. Tokamak-type reactors have come closest, but even they have not yet managed to remain perpetually active. 

Industrial processes and technology have been likewise overhauled and adapted to fit with the modern focus on lowered pollution, emissions, and environmental cleanliness. Factories are redesigned and rebuilt to work with the environment and with reduction of waste. Automation has also been a big part of this, and the power and processes used in manufacturing to entirely or at least primarily use renewable energy and resources. Alternatives to petroleum and oil derivatives have been extensively researched and implemented in manufacturing processes as well.

One area that still remains difficult to completely bring in line is that of resource extraction itself. Mining and the gathering and extraction of minerals and elements, especially rare ones, is still a huge industry and an essential part of running society at its' current level of sophistication and demand for such resources is only going up, rather than down. 
As such, those that can meet the demands are often sought out. There are many cases worldwide where agencies, groups, corporations, or national or regional governments have turned a blind eye, deliberately obfuscated, or outright used inhumane and aggressive force or tactics to claim deposits of vital or valuable mineral and material resources, displacing people, wildlife or rare biospheres to do so. There is a complex web of crossing paths and lines from all sides on these issues, and it is a very murky, shadowy area of global policy.
