How do battery electric cars work
Battery electric vehicles (BEVs) use electricity stored in battery packs to power motors, producing no tailpipe emissions and offering lower fueling costs than internal combustion engines. While their total pollution depends on the electricity source, they remain cleaner than gasoline cars even on coal-heavy grids. BEVs feature energy-saving technologies like regenerative braking and typically offer ranges between 70 and 265 miles.

We Can Protect Our Climate and Keep The Lights on Too!
The authors contend that the Clean Power Plan's design and current industry trends allow for significant power sector emission cuts while maintaining reliability. They highlight that existing natural gas and transmission infrastructure, combined with the flexibility of the rule, are sufficient to manage the transition. To further mitigate potential reliability risks, the document advocates for the EPA to establish a mechanism for interstate allowance trading between states in different regions, which would allow states facing local constraints to purchase allowances from those with surplus capacity.

Advancing Minnesotads Clean Energy Economy
The Union of Concerned Scientists argues that increasing Minnesota's renewable energy standard to 40 percent by 2030 would drive over $6 billion in new capital investments and reduce reliance on imported electricity without significantly impacting retail rates. The analysis indicates that such a policy would increase wind capacity to nearly 6,000 MW and utility-scale solar to over 600 MW by 2030. While a strengthened RES helps position the state to comply with the EPA's Clean Power Plan, the report notes that coal would still provide 38 percent of electricity in 2030 without additional policy actions. The authors recommend combining the strengthened RES with an increased energy efficiency standard of 2 percent annually by 2020.

Les prescriptions de résultats dans les traités d’investissements
The document examines performance requirements (PR)—stipulations imposed on investors to achieve specific development goals—and the legal constraints placed upon them by the WTO's TRIMs Agreement and various Bilateral Investment Treaties (BITs). It highlights a growing trend, led by Canada and the United States, toward broader prohibitions of PRs (MIC+ clauses) that extend to pre-establishment phases. Through the analysis of cases like Lemire v. Ukraine and Mobil Oil v. Canada, the guide illustrates the unpredictability of investment tribunals in interpreting these prohibitions. It concludes by offering strategic options for developing nations to maintain their regulatory space, such as avoiding PR prohibitions in BITs or explicitly excluding certain sectors and mechanisms from such restrictions.

Botswana’s Coal: Dead in the Water or Economic Game Changer?
Botswana possesses 212 billion tonnes of coal, offering potential for economic diversification away from diamonds. However, the document argues that a coal export industry is likely economically unfeasible due to massive infrastructure costs—specifically a proposed $10 billion railway to Namibia—and environmental constraints. Instead, the author suggests that integrating regional fossil fuels for electricity production could address Southern Africa's power crisis, provided there is political cooperation, particularly from South Africa, and until solar baseload power becomes a viable alternative.
