IRENA Releases World Energy Transition Outlook Report
- The COVID-19 crisis offers an unexpected opportunity for countries across the world to decouple their economies from fossil fuels and accelerate the shift to renewable energy sources, says the World Energy Transitions Outlook report, brought out by the International Renewable Energy Agency (IRENA).
- Previewed at the virtual Berlin Energy Transition Dialogue (BETD 2021), which began on Tuesday, the report proposes energy transition solutions for the narrow pathway available to contain the rise of temperature to 1.5°C and halt global warming.
- Highlighting the need for countries to change direction with careful recalibrating of stimulus packages and recovery measures, Director General of IRENA Francesco La Camera said, “The COVID-19 crisis has highlighted the cost of tying economies to the fate of fuels prone to price shocks.

Greedy Hedge funds push private equity firms around
- The M&A market is frothy and private equity firms are keen to put their vast funds to work. Many takeover targets are attracting several suitors. Hence, share prices have often traded above the level of the last offer, anticipating something higher will come along.
- When hedge funds are pushing private equity firms around, it’s hard to see things ending well. Merger arbitrageurs in the UK have been betting that deal-hungry buyout firms have infinite funds to pay sky-high prices for assets. But the arbs’ aggressiveness in driving up the shares of buyout targets may be a sign of something more troubling than optimism.

Mars' 'missing' water is buried beneath surface, says study
- Billions of years ago, Mars was home to lakes and oceans -- but where all the water went to transform the planet into the desolate rock we know today has been something of a mystery.
- Most of it was thought to have been lost to space, but a new study funded by NASA proposes that it didn't go anywhere but is trapped within minerals in the crust.
- "We're saying that the crust forms what we call hydrated minerals, so minerals that actually have water in their crystal structure," Eva Scheller, lead author of the new paper in Science, told AFP.
- In fact, Scheller's model suggests anywhere between 30 - 99 percent of the initial water remains trapped inside these minerals.
- Early Mars was thought to have enough water to cover the whole planet in roughly 100 to 1,500 meters (330 to 4,4920 feet) of ocean.
