Oil prices have fallen by more than half since July. Just five years ago, such a plunge in fossil fuels would have put the renewable-energy industry on bankruptcy watch. Today: Meh.

Researchers at Chalmers University of Technology have discovered that the insulation plastic used in high-voltage cables can withstand a 26 per cent higher voltage if nanometer-sized carbon balls are added. This could result in enormous efficiency gains in the power grids of the future, which are needed to achieve a sustainable energy system.

Ending a year-long race that had been nip-and tuck every month, renewable energy sources cumulatively provided more new electric generating capacity in 2014 than did natural gas.

For many mining companies, the rallying cry for investigating solar or wind energy options has been that the price of oil and other conventional fuels is too high — and will almost certainly rise over time. Now, though, with oil prices having taken a dramatic nosedive, this argument no longer packs quite the same punch that it once did.

India said cheaper credit along with foreign investment will help the world’s third-largest polluter fund an ambitious renewable energy program that would build green power plants faster than China.

The renewable energy industry has come a long way in relatively little time. The costs of renewable technologies continue to go down, while renewable capacities at many utilities continue to go up. Although, in many cases, renewable technology is mature and ready for utility-scale deployment, state and federal production and investment tax policies appear less evolved.

Iberdrola SA, Spain’s largest electricity company, agreed to buy UIL Holdings Corp. in a deal valued at about $3 billion in cash and shares to create a U.S. utility with about 3.1 million customers.

The annual outlook issue of Renewable Energy World magazine is our attempt to predict what will happen within the renewable energy industry over the course of the year. To do this, we went straight to the top of major renewable energy companies, asking CEOs and presidents to tell us where they are devoting their company resources in order to capitalize on some of the market growth that they expect to see in 2015.

In a must-read report released this week on fast-changing energy markets, the National Bank of Abu Dhabi signals a once-in-a-lifetime opening for investors in Middle Eastern renewables and energy efficiency.

Policies favoring clean energy and increased competition would normally dim prospects for existing producers. Not in Chile, where foreign investors are driving a renewable boom at a time of surging returns by local utilities.

Sweden and Norway agreed to boost their target for renewable energy production amid concerns the additional capacity will exacerbate a power glut and strain the region’s electricity grid.

The Russian Prime Minister Dmitry Medvedev has amended Russia’s federal law on the electric power industry. Ordinance No47 lays out a number of measures aiming to stimulate renewable energy sales in the national retail market.

Sen. Troy Fraser (R-Horseshoe Bay) has filed a bill that would eliminate Texas’ Renewable Portfolio Standard (RPS) – a policy that has catapulted Texas to world leadership in wind energy and strengthened Texas’ energy diversity. In addition to terminating the RPS at the end of the year, SB 931would make it more difficult to build renewable energy infrastructure. The argument behind the bill is that because Texas has achieved its RPS goals it’s time to move on. Sounds reasonable, right? Well…

In our second annual survey on American homeowners’ attitudes toward clean energy, one thing is resoundingly clear. In a nation divided on climate change, immigration policy, and so many other issues, Americans are overwhelmingly united in their support of renewable energy.

We've made great progress with renewable energy — but from an almost zero base we still have a long way to go. Fortunately, the path is clear. California is already over 12 percent with a combination of hydroelectric, wind and solar (unfortunately not much hydro this year). Getting to 50 percent only requires the deployment of existing technology. But can we get to 100 percent?

Brazil will increase the use of renewable energy, target zero net deforestation and push for low-carbon agriculture as part of its climate proposal, Environment Minister Izabella Teixeira said in an interview.

Just over a decade ago, the state of California faced serious concerns about whether its utilities could generate and/or buy enough power to assure that the world’s seventh-largest economy could keep the lights on. The infamous California energy crisis, which affected several other western states as well, was a complex tangle of poorly structured deregulation, significant market manipulation (remember Enron?), and other causes. Along with rolling blackouts, California endured an official state of emergency that lasted 34 months, led to the recall and replacement of Gov. Gray Davis, and cost the state and its ratepayers billions of dollars — a cautionary tale for all states of electricity supply unable to meet demand.

Turns out that Americans are a bit overly optimistic about the role that renewable energy plays in the U.S. The average American believes that 20 percent of the country’s energy use comes from renewables—11 percent from solar and 9 percent from wind.

This week at the Assembly of the International Renewable Energy Agency (IRENA), political and business leaders from around the world outlined the far-reaching geopolitical implications of an energy transformation driven by the rapid growth of renewable energy.

The fallout from California power giant PG&E Corp.’s looming bankruptcy has been both sudden and widespread: Its electricity suppliers have seen their debt cut to junk. Banks are facing liabilities as buyers of last resort for more than $760 million of bonds the utility issued through California. And the rest of the state’s utilities have tumbled.

Utilities and renewable-energy advocates have long had a complicated relationship. Yet the prospect of PG&E Corp. tipping into bankruptcy by the end of January has sent shivers through the solar-and-wind sector.

EIA expects non-hydroelectric renewable energy resources such as solar and wind will be the fastest growing source of U.S. electricity generation for at least the next two years. EIA’s January 2019 Short-Term Energy Outlook (STEO) forecasts that electricity generation from utility-scale solar generating units will grow by 10 percent in 2019 and by 17 percent in 2020. According to the January STEO, wind generation will grow by 12 percent and 14 percent during the next two years. EIA forecasts total U.S. electricity generation across all fuels will fall by 2 percent this year and then show very little growth in 2020.

Corporations signing PPAs with renewable energy power producers have been on the rise for quite some time but in 2018, the group as a whole purchased more than double the clean energy they purchased in 2017.

GE announced today that it sees a future in housing its renewable generation businesses (onshore and offshore wind, hydropower) alongside its grid businesses which include substations and transformers plus solar, storage and distributed energy resource (DER) control software.

PG&E Corp. is seeking court protection to amend or cancel power purchase agreements with suppliers as part of its bankruptcy proceedings.

The global strategy for mitigating climate change is no secret. Most countries have embarked on an initiative to transition to clean energy sources. According to a study by scientists from the universities of Oxford and Utrecht, we will almost certainly pass a point of no return for dealing with global warming if governments worldwide don’t transition away from fossil fuels, such as coal and natural gas, towards renewable energy by 2035. This would mean that renewables would need to see their total share of power generation increase by at least two percent per year.

Australian hydrogen infrastructure developer H2U confirmed today that it will use Baker Hughes NovaLT gas turbine generators at its South Australian Renewable Hydrogen and Ammonia Supply Chain Demonstrator in Port Lincoln.

According to an analysis by the SUN DAY Campaign of data just released by the Federal Energy Regulatory Commission (FERC), natural gas dominated new electrical generating capacity in 2018. However, renewable energy sources (i.e., biomass, geothermal, hydropower, solar, wind) seem poised to swamp fossil fuels as new generating capacity is added over the next three years.

When Hurricane Maria devastated Puerto Rico, it cut short nearly 3,000 lives, displaced thousands of families, and subjected the commonwealth to the longest energy blackout in U.S. history. This tragedy invited a new vision for Puerto Rico’s battered electric grid, and I hoped that a central tenet of the rebuilding effort would be an aggressive move toward safe, abundant and resilient clean energy.

What happens when a famously left-leaning city dives into the buttoned-down business of electric utilities? San Francisco may soon find out.

On Friday, New Mexico Gov. Michelle Lujan Grisham signed the state’s groundbreaking Energy Transition Act (ETA) into law, meaning that by 2045, the state should be fully powered by clean, carbon-free electricity.

It was a milestone deal, not for its size but for the number of parties. In January, five big companies, each with differing energy requirements and renewable strategies, agreed to pool their investment and collectively purchase 42.5 megawatts from a North Carolina solar project.

In a first for the country, Germany generated 54.5 percent of electricity from renewable energy in March 2019. This is according to data collected by the Fraunhofer Institute for Solar Energy Systems.

Recently there has been a great deal of interest in a ‘Green New Deal’ for the United States. It is seen as a way to solve pressing environmental, employment and economic problems with a single comprehensive plan. Modeled on Roosevelt’s New Deal, which created jobs, invested in large infrastructure projects, and pulled the US out of the Great Depression, the Green New Deal is a modern version of that program, but with green energy investments, 21st century job training, and deficit reduction as the key components.

Cities and renewable electricity have, respectively, become the habitat and energy of choice globally. The two are increasingly inseparable. Urbanization and electrification trends have turned cities and the grid into leading platforms for human activity, presenting unique opportunities for today’s utilities to partner with municipalities to achieve their smart city goals.
