By 2030, how green will be the future of energy?

How can the energy industry adapt to meet the needs of a growing population while also supporting low-carbon growth? Katherine Hamilton, Director of the Project for Clean Energy and Innovation, and co-chair of the Global Future Council on the Future of Energy, says that this essential transition will not happen without collaboration between large energy companies, entrepreneurs, the finance sector and consumers.

The energy sector is already changing very rapidly. It is transitioning, we hope, towards greater ability to meet the energy needs of a growing global population with reduced use of carbon, supporting continued economic growth in an environmentally sustainable way.

But that transition will not necessarily happen on its own. We need to get key players in the same room who can bring different experiences and perspectives, and collectively come up with better ideas than any of us could on our own – and then work out how to implement those ideas. Hence the need for this Global Future Council.

The incumbents are important, of course – the large energy companies who own and control the infrastructure, especially in industrialized countries. They are often criticized as part of the problem, but they also have to be part of the solution. In addition, we need the innovators – entrepreneurs who are coming up with ideas to disrupt the sector. And we need input from energy consumers, including large corporations and municipalities.

Representatives of the financial sector are important – experts in bonds, risk and insurance. There is plenty of capital out there looking for good projects to finance, but the main constraint for investors is the assurance that those projects will find a market. Creating certainty is one important thing politicians and policymakers can do to help – and it is they who, ultimately, will need the vision to define goals for the energy sector and devise policies to achieve them.

The decentralization of energy generation is an enormous trend. Innovation is also being democratized; it is no longer just the incumbents who can innovate. Consumers, increasingly, are in the driver’s seat; there is more real-time interaction between energy service providers and consumers – whether that is the operator of a factory with sophisticated demand response or an Indian farmer using a mobile phone to manage crops.

We are continuing to see drastic reductions in the cost of many renewable technologies as well as greater accessibility to energy storage and efficiency and a brighter future of energy.

Any time you talk about subsidies for renewables, you also have to remember that incumbent players have benefited from built-in subsidies for decades through policy support and monopoly power. Often there is a misconception that energy was a free market before the idea of subsidizing renewables came along. That is not the case, and we need to recognize that when we ask how best to adjust the market for innovation going forward.

The sharing economy will be increasingly important in the transport sector. There is potential to improve efficiency and greatly reduce emissions as we move towards more electric and autonomous vehicles.

There is also room to harness data to make the grid and the entire energy ecosystem more efficient. The data is available, through advanced meters and mobile applications, for example, but we have yet to fully exploit that data to move energy to where it is needed, smartly and in real-time.

I expect to see more “community solar” projects, as collective consumers invest in generating and storing power. There will be more distributed generation using a variety of technologies, such as solar, wind, geothermal, fuel cells, and hydropower. We will see further innovations in the future of energy, like, in multiple uses of energy storage, such re-purposing car batteries to store electricity.

In the coming years we might see some breakthroughs in carbon capture and storage – and, no doubt, there will be innovations and applications nobody has thought of yet.

Above all, for a green future of energy, we must have a solid plan to reduce carbon. To reach that, we have to define what we value – not just improving access to energy and guaranteeing energy security to meet the needs of economic growth, but doing all of this in a sustainable way and one in which carbon emissions are drastically reduced. Then we need clear and transparent benchmarks against which to measure our progress.

We also need a vision that combines the decentralized and the centralized – embracing more distributed generation, while looking at the larger system and how we can move energy around globally in real time.

I fear that we will be paying for our previous failures to reduce carbon emissions, and being increasingly preoccupied with climate change adaptation. But I also believe that we can have a sector that delivers much higher access to energy than today, with greater use of renewables, incentivizing innovation and creating economic growth while reducing our impact on the planet.
