  13. 13. Global CO2 Emissions from Fossil Fuels by Sector
  14. 14. ▪ Global emissions from 2014-17 grew in total by 1.6%. ▪ This substantial slowing in emissions is historic in that it is not coupled with the GDP trend, as cumulative global GDP grew by almost 9 percent. ▪ The reduction is associated with “a more structural change with a shift away from carbon-intensive activities, particularly in China but also in the United States (p. 12).” Source: Observations on global emissions from fossil fuels
  15. 15. Summary ▪ Rapid rates of technical of advance • Solar • Wind • Systems integration ▪ Cost levels of renewables, especially solar and wind, are clearly in competitive ranges. • Continued technical advance, which is expected, will place more renewables as least cost (subject to systems integration). ▪ Renewable generation share is becoming significant • Implications of the next two doublings of renewable power share much more profound than the previous two doublings.
  16. 16. Systems integration at center stage ▪ Wind power generation is highly variable on a turbine by turbine basis. ▪ Solar PV is not available at night and is strongly reduced with clouds. ▪ Systems integration matches supply with demand • Dispatchable supply • Demand management • Storage/Batteries

  21. 21. Global looking forward ▪ Variable renewable sources are highly likely to represent rapidly increasing shares of electricity generation. ▪ Those best able to profit from this energy revolution will have: • Endowments in renewable resources, notably solar and wind, but also complementary dispatchable resources including hydropower. • Needs for distributed power. • The ability to systems integrate.

  23. 23. The energy revolution and Africa Those who will profit most are likely to have: 1. Endowments in renewable sources, notably solar and wind, but also hydropower. 2. Needs for distributed power. 3. The ability to systems integrate. Broadly, good news for Africa

  29. 29. Serious Transition Issues ▪ In South Africa (and almost everywhere else), institutions are designed to burn fossil fuels and transmit power, often via state-owned monopolies or a tightly regulated private sector. ▪ A decade ago, some optimism existed that carbon capture and storage technologies would allow this structure to persist. ▪ But, this has not happened. ▪ Instead, a new paradigm reliant on variable renewable energy (VRE) is emerging.
  30. 30. Installed electricity capacity Electricity price by component price of electricity is 14% higher in 2050 – VRE replaced by nuclear and coal Constraining VRE (keep VRE out) raises the costs of power generation

  32. 32. Large Opportunities and Challenges ▪ Rural electrification • Genuine potential exists to extend access to electricity to the nearly one billion people who lack it by 2030. • But, it won’t happen by itself • See IFPRI’s 2019 Global Food Policy Report ▪ Energy and development • Clear capability to develop clean, reliable, and low cost systems, particularly in developing countries. • But, must develop the ability to systems integrate. • And confront entrenched interests and habits in the power sector as well as design and implement ‘a just transition’ from coal and other affected industries.
  33. 33. Forward Thinking Questions ▪ What policies, programs, and institutions are required to realize the enormous potential for rural electrification? ▪ What are some potential downstream consequences to rapid rural electrification? • Women’s empowerment? • Large scale solar pumping and groundwater resources? ▪ How to deploy hydropower in a VRE dominated system? ▪ How should grid build plans and rural electrification strategies interact? ▪ What are the benefits of modularity of VRE systems? ▪ What institutions and regulatory framework are best suited to handling substantial VRE dependence?
