Generating less electricity with fossil fuels could help save lives.
Heads of state attended the G7 summit in La Malbaie, Quebec, on June 9, 2018. Top row: European Council president Donald Tusk, UN Secretary-General António Guterres, International Monetary Fund Managing Director Christine Lagarde. Bottom row: Seychelles President Danny Faure, French President Emmanuel Macron and German Chancellor Angela Merkel. US president Donald Trump’s recent protectionist moves were at the top of the agenda.
After the G7 fiasco, it's clear that a trade war is in the making. US justifications of "national security concerns" for its tariffs suggest a legitimate target for EU countermeasures: coal.
The latest research suggests that in Australia, rooftop solar photovoltaics are more likely to be adopted by middle-class households.
Households that are most likely to go solar are those that can afford solar panels, but aren't so rich that they don't have to worry about their electricity bill at all, says a survey of 8,000 homes.

They may not say 'climate change,' but many Republican US mayors support clean energy, jobs in renewable industries, and other climate-friendly policies. And so do majorities of their constituents.
Solar lowers prices and shifts when daily peak demand hours are.
Large-scale solar and wind tend to push energy prices down, which sounds great as a consumer. But that makes keeping the grid in constant balance harder.

Environmentalists and climate hawks are cheering, but many experts aren't excited about the state making rooftop solar panels mandatory on most new homes beginning in 2020.
Ammonia production is one of the most energy-intensive industrial processes on the planet.
Producing ammonia, which is a key ingredient in fertilizers, is one of the world's most energy-intensive chemical manufacturing processes. Now there's a new low energy option in development.

There are some big misconceptions about the charcoal sector and its role in environmental damage
Mass. Gov. Charlie Baker signed a comprehensive energy law in 2016 that authorized the development of new offshore wind and hydroelectric projects.

Several states, including Massachusetts and Rhode Island, have developed ambitious renewable energy targets that hinge in large part on getting their power from turbines stationed in the water.
China has its eye on technological dominance.
Now is the time for China to put its technological and diplomatic skills on display in its quest for superpower status.

Deriving fuel from trees costs more than wind and solar power and it emits more carbon than coal. There are many heated debates about this kind of energy, known as forest or woody biomass.
Annual water requirements of a PHES-supported 100% renewable electricity grid would be much less than the current fossil fuel system, because wind and PV do not require cooling water.
Wind turbines are becoming as American as haybales.
While wind energy is often perceived as controversial, that may be due to the tyranny and power of unrepresentative anecdotes.

Politicians and economists call for emissions cuts while also embracing free trade – they can't have it both ways.

Experts expect the wind business to remain brisk in the US and abroad, on land and offshore.
Rising seas, harsher weather, rainier days. The impacts of climate change make it harder for Caribbean countries to plan their transition toward renewable energy sources.
The 2017 hurricane season showed that Caribbean nations urgently need more resilient power grids. But the effects of climate change – including more severe storms – complicate the shift to renewables.
Block Island Wind, the first offshore wind energy project in the U.S., started operation in 2016.
A recent survey of electric utility leaders finds that Trump administration efforts to promote coal energy and roll back air pollution regulations have had little impact on their long-range plans.
Josh Frydenberg met with state energy ministers in Melbourne the latest round of discussions over the National Energy Guarantee.

The federal government is confident that states will sign up to the National Energy Guarantee, with a final decision now timetabled for August.
Tesla is installing one of the world’s largest solar arrays at its Gigafactory 1 in Nevada.
Will the renewable energy transition end up creating yet more greenhouse emissions, as we ramp up the manufacture of wind turbines and solar cells? Not if their manufacture is itself powered by renewables.
