A road to nowhere?

Solar roadways have been promoted as a way to fight climate change, put people to work and make driving safer. But on closer inspection the reality is less than impressive.

The case for pragmatism, not dogma.
Access to water – not electricity – can have larger gains for health and well-being.
Providing people with clean drinking water and sanitation is less expensive than grid electrification and it could improve more lives.
This roof in Newcastle has become the first in Australia to be covered with specially printed solar cells.

The first commercial-scale installation of rooftop solar cells, printed with specialised inks, is a step towards an energy future in which solar power can be stuck to any roof or structure.
The shrinking supply of Colorado River water is evident at the Hoover Dam on the border of Arizona and Nevada.

Taking millions of gallons of water permanently out of the Colorado River amid a prolonged drought would surely start an interstate fight.
The number of coal mining jobs has gone up slightly, but many times less than solar-related ones.

The Trump administration's Affordable Clean Energy Plan would help the declining coal industry, but a study shows many coal workers could transition to a new industry – solar – and earn more money.
Analysts hope that South Africa’s new energy plan will have wind and solar plans.
South Africa's new energy plan is set to be announced.
Can Walmart go green while maintaining its commitment to low prices?

Two business professors spent five years studying Walmart's ambition project to bring sustainability to its millions of budget-conscious customers – a plan that began with the birth of a granddaughter.
What if it were a lot easier to install solar power?
Silicon is cheap and a good semiconductor, but it's bulky and rigid. Using organic polymers as semiconductors could yield solar panels with the physical characteristics of plastics.
Energy experts are getting excited about a proposed solar farm in Kent and what it could mean for a clean energy future.
Understanding how certain proteins deal with light absorption can inspire modern solar technology.
Proteins guard their secrets closely, but once you get them to "sing", there's an enormous amount to learn.
As the name suggests, Windy Hill near Cairns gets its fair share of power-generating weather.

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.
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.

Solar power technology has huge potential for Africa. But there are some barriers.
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.
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.
The coils winding facility building in France, where a global effort to build the ITER fusion energy reactor is underway.
As fusion becomes more technically viable, it's time to assess whether it's worth the money because breakthroughs in the lab don’t guarantee success in the marketplace.
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.
