Frequently Asked Questions

What is the Clean Power Hub?

The Clean Power Hub is a new platform to help power sector professionals get their work done faster. It enables faster sharing of clean power know-how through practical, action-oriented guides and expert support. Read more here.

Who is the Clean Power Hub for?

The Clean Power Hub supports the work of the people and institutions that are leading the global transition to clean power, including planning, policymaking, regulation, modern electric grid operations, investment and project development, and effective communication and advocacy. So, if you’re doing this work, or want to be doing more, the Clean Power Hub is for you. It’s here to help you get your work done, better and faster.

What do you mean by "clean power"?

The Clean Power Hub focuses primarily on electricity production from wind turbines and solar PV, the fastest growing power sources that don’t create air pollution or contribute to climate change. Generation from these sources will exceed that of hydropower in 2024, and renewables (including hydropower) will become the largest source of electricity generation, surpassing coal, by 2025 (all data from IEA, Renewables 2020).

The Clean Power Hub emphasizes the practical aspects of the development and integration of wind and solar power into electricity systems at utility scale and in the form of distributed energy resources (DER). This includes the planning, policy, regulatory, and operational changes necessary for successful integration of these sources. Integration of large shares of renewables is no longer a question of technology readiness or cost, but is instead one of identifying the work needed and getting it done. The Clean Power Hub is here to help.

Why doesn't the Clean Power Hub focus on hydropower or nuclear power?

Hydropower and nuclear power are long-established means of providing electricity without carbon or air pollution. However, not all countries have these resources, or they may choose to not use them because of environmental, social, or other considerations. In contrast, all countries have access to some degree of renewable energy resources, and these resources are increasingly the lowest cost forms of generation. Finally, the work needed to add large baseload sources like hydropower and nuclear to a power system is widely-understood and relatively straightforward, making the need for a tool like the Clean Power Hub less relevant for these sources.

What about energy efficiency?

Large-scale energy efficiency programs are consistently the most cost-effective means of meeting rising electricity demand and reducing pollution, including carbon emissions. Power systems around the world would be wise to implement or enhance such programs.

However, energy efficiency alone can’t meet all additional demand or solve all pollution and climate change problems, particularly in rapidly-growing economies. Also, the expertise required to design and implement energy efficiency programs is quite different from that required for integration of renewables into power systems. For these reasons, the Clean Power Hub does not, at present, offer resources that focus on energy efficiency programs. One critical exception is flexible demand response—essentially deploying energy efficiency in a targeted way as needed to benefit the power system. Flexible demand response is a key tool for power system operators. Learn more in this section of the Clean Power Hub.

What about off-grid solutions like minigrids or solar home systems?

With the falling cost of renewable power generation, minigrids or solar home systems may be the least expensive option for providing energy services to rural communities. The increasingly important concept of integrated electrification planning takes into account the option of providing energy services with off-grid power sources. While the Clean Power Hub is currently focused on grid-connected clean power sources, we plan to include some content related to off-grid electrification in the near future.
