The energy revolution is here

Oct 13,2019 - Last updated at Oct 13,2019

BOULDER, COLORADO — For the longest time, the prevailing narrative about renewable energy featured clumsy technologies, high costs and burdensome subsidies. In the absence of strict mandates and far-reaching policy changes, the chances for mass adoption seemed slim. Electric vehicles (EVs) simply could not go the distance, and LED lights were unattractive and unaffordable.

But now that these technologies have come of age, a new story is being written. Around the world, businesses, governments and households are taking advantage of more cost-effective, low-carbon technologies. Owing to advances in information technologies (IT), green solutions can be integrated into business operations seamlessly. And as public support for these technologies has grown, so have the prospects for scaling up to a fully sustainable energy system.

As in any rapid transition, a full understanding of what is happening has lagged behind events. Many incumbent energy producers find it hard to believe that their world is undergoing a revolutionary change, so they insist that their heavily polluting technologies will remain relevant and necessary for some time to come. Journalists, too, describe the transition with a degree of caution, because it is their job to be skeptical. And politicians and regulators are reticent to adopt a new perspective, even though they are already struggling to keep up with the pace of change in the energy industry.

To be sure, progress does not come without setbacks, as the recent growth in energy-related greenhouse-gas (GHG) emissions shows. Yet there is no doubt that the future of energy will be dramatically different from the recent past. In fact, the transformation is happening even faster than we think, owing to three key factors.

First, sustainable-energy technologies are quickly becoming more cost-effective than the alternatives, enabling businesses to reduce pollution, increase efficiency and provide more goods and services. The costs of technologies ranging from wind and solar power to EVs and smart grids have plummeted, and the learning curve, the linear drop in costs as new technologies are deployed on an ever-larger scale, has held steady across the board. The cost of installing utility-scale solar panels fell by 80 per cent from 2010 to 2018. Likewise, the cost of lithium-ion battery packs dropped by 69 per cent from 2014 to 2018; the price of LEDs declined six fold in just four years, from 2010 to 2014. What was once pricey is now cost-effective; it will soon be downright cheap.

Moreover, the pace of innovation is not slowing. Spending on clean-energy research and development is increasing, and more clean-energy patents are being filed than in years past. The clean-tech sector is attracting more young entrepreneurial talent, and venture capital spending is on the rise.

More broadly, there is a clear cross-sector shift toward low-carbon technologies and business models. The traditional energy companies that are not in denial are increasingly investing in the technologies of the future, as are the automotive giants. And a growing share of large-scale infrastructure capital is beingdeployed in innovative ways, accelerating the transition.

Second, while each breakthrough makes a big difference on its own, the combination of new technologies magnifies the impact. Big Data is already enabling better forecasting of wind and solar production and demand, leading to a much higher share for renewables in the energy mix. The falling cost of batteries not only accelerates the diffusion of EVs, but also allows them to store power for the electricity grid. And, more broadly, IT has enabled smart-timed EV charging and other methods for making the grid more flexible and efficient.

Moreover, as the costs of renewable energy fall, wind and solar power can be used to produce hydrogen, another clean-energy source that may be more suitable for economic sectors, such as air transport, that have so far struggled to shift to low-carbon fuels. And, looking ahead, the next frontier of sustainability may lie in blockchain technologies, which could facilitate “trade” in surplus electricity among consumers in innumerable, instantaneous transactions.

Finally, the political environment is rapidly changing. A decade ago, there was no Paris climate agreement, financial institutions were not accounting for climate-related risks in their investment portfolios and most industries were as committed as ever to fossil fuels. All of that has changed.

Even in the United States, where US President Donald Trump continues to champion high-carbon energy sources, coal-fired power plants are shutting down faster than ever, and plans for new natural-gas plants are being replaced with more cost-effective wind and solar options. And as the shift toward renewables gains momentum, it will be easier for elected officials to pursue more climate-friendly policies and regulations, thereby creating a virtuous circle of change.

As the green transition comes of age, it will offer solutions to all of humanity’s energy needs, placing a clean, prosperous and secure low-carbon future well within reach. Yet even as we embrace optimism, we must not lose sight of the fact that climate change is accelerating. With GHG emissions continuing to rise, the future of humanity hangs in the balance. One hopes that the shift to sustainable energy will tip the scale in our favour.
