Can a power sector transition to 100% re supply?

Transition for the power sector Transitioning of an isolated power sector towards 100% RE supply seems to be the least challenging part: no new capacity needs to be built in the initial years of the transition due to existing overcapacities.

Should the US limit additions of wind and solar power?

And only 15% of respondents said the US should limit additions of wind and solar power due to reliability concerns. The concern appears to be more of a recognition of the investment and effort it will take to integrate these variable resources.

What is the optimal share of electricity generation in 2050?

In 2050, the optimal share of wind-based generation decreases to 28% of the total electricity generation, while the share of solar PV increases to 67%. The share of hydropower and biomass in the power generation is limited.

What is the share of PV in total capacity and generation?

The share of PV in the total capacity and generation slightly increases from nearly 73% of the total generation for power, heat and transport to 78% in case of all energy sectors integrated. The share of hydropower and biomass decreases due to reaching the maximum technical potential limit and growing electricity demand.

Why does the energy transition require a long permitting process?

In addition to policy instruments that mandate or support the deployment of renewable energy, the energy transition requires an enabling environment for the development of projects. Especially for wind projects, long permitting processes can slow deployment due to the associated set of rules and regulations.

How do governments and development partners contribute to the energy transition?

Finally, for the energy transition to have a positive impact, governments and development partners need to play a more active role in ensuring a more equitable flow of finance that recognises the different endowments and starting conditions of countries.
