Insurers are easing adoption of large-scale energy storage

German insurance company Munich Re will now offer long-term insurance on battery performance in energy storage systems, a move that could reduce barriers to investment in energy technologies.

Why it matters: Large-scale renewable energy systems are expensive and complex, and in some cases their manufacturers have declared bankruptcy before the end of their systems' maintenance and warranty periods. Insuring against such risks — as well as those associated with relatively untested new battery chemistries — could spur adoption of innovative technologies by utilities and transportation providers and in off-grid applications.

Sri Lankan attacks underscore continued threat of jihadist groups

The terrorist attack Sunday in Sri Lanka that killed 290 — including several U.S. citizens — and wounded another 500 was among the top 5 deadliest attacks outside of a war zone since 9/11. The group blamed by the Sri Lankan government for the attack, National Thowheeth Jama’ath, was not publicly known in the West.

Why it matters: The Sri Lankan attacks are an important reminder that jihadist terrorism remains a significant threat, especially in the region spanning West Africa to Southeast Asia. There are at least 3 times as many Islamic extremists in the world today as there were on 9/11. This form of terrorism could persist for generations.
