Grid Flexibility

Electricity Generation

For electricity supply to become predominantly or entirely renewable, the grid needs to become more flexible and adaptable than it is today.

Grid Flexibility

What do these numbers mean?

TOTAL CO2-EQ REDUCTION (GT)

Total CO2-equivalent reduction in atmospheric greenhouse gases by 2050 (gigatons)

NET COST (billions US $)

Net cost to implement

SAVINGS (billions US $)

Net savings by 2050

Impact:

We do not model grid flexibility because it is a complicated, dynamic system, and it is nearly impossible to account for all local factors at a global scale. However, to grow beyond a 25 percent share of generation, variable renewable energy sources require grid flexibility. The emissions reductions from this solution are counted in the variable renewable solutions that could not reach their full potential without it.

Family Planning

Women and Girls

Securing women's right to voluntary, high-quality family planning dramatically improves the health and well-being of women and their children. It also avoids emissions.

Impact:

Increased adoption of reproductive healthcare and family planning is an essential component to achieve the United Nations’ 2015 medium global population projection of 9.7 billion people by 2050. If investment in family planning, particularly in low-income countries, does not materialize, the world’s population could come closer to the high projection, adding another 1 billion people to the planet. We model the impact of this solution based on the difference in how much energy, building space, food, waste, and transportation would be used in a world with little to no investment in family planning, compared to one in which the projection of 9.7 billion is realized. The resulting emissions reductions could be 119.2 gigatons of carbon dioxide, at an average annual cost of $10.77 per user in low-income countries. Because educating girls has an important impact on the use of family planning, we allocate 50 percent of the total potential emissions reductions to each solution—59.6 gigatons a piece.
