There are calls from the backbench and elsewhere for the federal government to safeguard the future of coal. But do those calls make economic sense? A look at Queensland's energy landscape suggests not.
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.
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.
Solar photovoltaics are now the world’s leading source of new electricity generation.

Solar photovoltaics and wind power are on track to supplant fossil-fuel-based electricity generation by the 2030s. The only thing holding back the renewable revolution is politics.
Grid-scale energy storage systems may make it easier to rely completely on renewable energy.
Saving power to use later lets consumers, businesses and utilities generate energy when it's cheap and deliver it when they need it most. There's not much of it today, but the industry is growing fast.

The fossil fuel era won't last forever. And a new set of countries will find their reserves of lithium, copper and rare earth metals are in high demand.
The Loy Yang power station ‘tripped’ early in the year, triggering fears of a summer of blackouts.
February is the riskiest time of the year for blackouts, as the nation returns to work and school and soaring temperatures put pressure on the system.

On Q&A, an audience member said renewable energy is 'now cheaper than coal'. Senator Matt Canavan disagreed, saying renewables are not 'at the moment, cheaper than coal'. Let's look at the numbers.
As more wind turbines have been put in place, the cost of wind energy has gone down.

If history is a guide, policies that promote wind power expansion will lead to lower prices – potentially beating fossil fuels in the US by 2030.
Solar PV outstripped coal as the leading source of new electricity generation worldwide last year.

Solar PV and wind energy have overtaken coal as the leading sources of new electricity generation worldwide, with falling prices and new storage technologies making clean energy ever more attainable.
The UK is about to miss an opportunity if it tries to take on the giants of the lithium-ion battery industry.
Lessons from the Lone Star State: A surge in wind power on the Texas grid didn’t cause reliability problems (and brought down electricity prices) because regulators improved the efficiency of wholesale electricity markets.
