Shell boosts renewables push in U.S. and Asia

Driving the news: Shell unveiled a joint venture with EDF Renewables North America, an arm of France-based global power giant EDF Group, to develop a wind energy lease off New Jersey's coast.

• Separately, Shell said it has acquired a 49% stake in Cleantech Solar, a Singapore-based developer with projects in southeast Asia and India. The costs were not disclosed.

Plus, on the solar front, early this year Shell said it's spending $217 million to acquire a 44% stake in the U.S. solar power developer and operator Silicon Ranch.

• Shell has also been moving into EV charging and other power initiatives beyond its core oil-and-gas business.

But, but, but: Big Oil's clean energy investments remain a very small part of their portfolios.

The bottom line: For perspective, the amount oil majors as a group have spent on renewables since 2016 represents less than 3% of their exploration and production spending, according to Wood Mackenzie.

The consultancy said in a note this week that they expect renewables spending to grow just slightly in 2019.

• "Companies and investors will be wary of backing the wrong horse in new energy. It’s a sector they are still trying to understand," said WoodMac analyst Tom Ellacott.
