If you're reading energy news of late, you might have come across three new ways that forces are aligning against local renewable energy. State governments are increasingly pre-empting local authority on a range of issues, including energy. Utility companies are undercutting state regulation with their legislative lobbyists. And utilities are also bringing their monopoly market power to bear in previously competitive markets.

As world leaders prepare to convene in Hamburg, Germany later this week for the annual G20 summit, it is clear that climate is set to be a key issue. But with the Paris Agreement at the forefront of the world’s stage, how do the energy investments of the G20 countries align with their international climate commitments?
German solar battery maker sonnen is offering Australian households “free power” in a deal to increase its foothold in the local energy storage market.
And in a major coup, the company has signed up the same supplier and installation firm that installs Elon Musk’s rival Tesla Powerwall system — Natural Solar.

On this week’s Interchange podcast: A “loose federation of weirdos” discusses the potential role of blockchain in electricity markets.
The report, released July 5, is the product of research conducted by Oil Change International, Friends of the Earth, the Sierra Club, and the World Wildlife Fund's European Policy Office. Their goal was to parse out the amount of public financing — defined as grants, equity, loans, guarantees, and insurance from majority government-owned financial institutions— that various G20 countries have given to domestic and international energy production.

I have been promoting “no money down” solar financing since the late 1990s when I wrote the business plan for SunEdison. In the interim years, I have become dismayed by how little we have been able to democratize solar financing. Consider this: how many people do you know who engage in real estate investing outside of more typical day jobs? I can think of several off the top of my head, and there are even reality TV shows dedicated to “flipping” houses.

The concept is sound. PACE state enabling statutes generally authorize local governments to engage private sector lenders to provide upfront low interest financing to commercial property owners for energy efficiency, water conservation and renewable energy projects (e.g., HVAC system upgrades, photovoltaic system installations, replacement cool roofs, etc.) collecting the repayment through annual assessments on the property’s real estate tax bill.

hey are the mini-computers being installed in 30m UK homes and businesses in an £11bn programme that will allow the energy companies to remotely monitor our gas and electricity usage. But could smart meters also become the new spies in our homes, raising fresh fears about a surveillance society as they track our daily activities?
The Sierra Club released a new analysis Friday that found that transitioning all 1,400+ U.S. Conference of Mayors member-cities to 100 percent clean and renewable electricity will significantly reduce electric sector carbon pollution nationwide and help the U.S. towards meeting the goals of the Paris climate agreement.

Congress is likely to tackle federal tax reform in 2017 and may consider new ideas. One proposal it should seriously consider is clean tax cuts—the application of supply-side tax rate cuts to investments that reduce the emissions of harmful pollutants. Cutting tax rates on income gained from clean investments such as energy efficiency improvements could incentivize investors to tap large amounts of private capital.

The world is entering an era of "base-cost renewables", when the cheapest source of incremental power generation in most countries will be ultra-cheap renewables. Does that doesn't mean policy-makers can step away and the unfettered free market will deliver the rest of the clean energy transition? Unfortunately not!

The United States, China and India are vying to be the market leader, and are looking out for any perceived breach of the international trade rules by their rivals.
Last September, the WTO ruled that India was illegally discriminating against U.S. solar exports, while India launched its own WTO complaint about solar subsidies in eight U.S. states.
The United States' ability to attract renewable energy investment has been tarnished by the shift in energy policy under U.S. President Donald Trump, putting China and India on top, a report by British accountancy firm Ernst & Young said earlier this month.
Jobs in the sector of renewable energy is likely to reach 24 million by 2030 globally and become a major economic driver around the world, according to latest report published by Abu Dhabi based International Renewable Energy Agency (IRENA).
The agency in its Jobs Annual Review 2017 report mentioned that employment in the renewable energy sector increased by 2.8 percent to reach 8.3 million in 2016, with India, United States, China, Japan, Brazil and Germany being the leading job markets.
The number of jobs in wind and solar power sectors has more than doubled in the last four years.

Electricity grids are some of the most complex systems ever invented. Serving millions of homes and businesses across thousands of miles of transmission and distribution lines, they’re an incredible tangle of electron flows. And, compared to other infrastructure, they’re generally not very up to date: much of the design still dates back to Thomas Edison and Nikola Tesla.

Billing analysis, Bayesian statistics, randomized control trials, phone polls — with the advent of EEMetering, smart meters, and pay-for-performance, one of the most important questions we have to answer as an industry is how do we measure energy efficiency?
Turns out, it depends on the purpose.
While the art of evaluation for regulated programs is well established, the movement of energy efficiency towards pay-for-performance markets and procurement requires a rethinking of how efficiency is regulated, measured and transacted.

The Greens believe there should be an independent authority like the Reserve Bank to oversee the switch to renewable energy to avoid political squabbling at federal and state levels.
Greens MP Adam Bandt says the system is broken with the federal government attacking the states and 'waging a war' on renewables, rather than try to fix it to ensure power bills stay low and the lights stay on.

The new 115th Congress is now underway. Despite the current great political divide in Washington, there is a glimmer of bipartisanship.
Senators Rob Portman (R-OH) and Jeanne Shaheen (D-NH) have reintroduced the “Energy Savings and Industrial Competitiveness Act” (S. 385), better known as the Portman-Shaheen Act. Early co-sponsors of the bill are Senators Michael Bennet (D-CO), Susan Collins (R-ME), Chris Coons (D-DE), Al Franken (D-MN), Joe Manchin (D-WV), Mark Warner (D-VA), and Roger Wicker (R-MS).

The latest GDP numbers from the World Bank were released earlier this month, and today’s visualization from HowMuch.net breaks them down to show the relative share of the global economy for each country.
The full circle, known as a Voronoi Diagram, represents the entirety of the $74 trillion global economy in nominal terms. Meanwhile, each country’s segment is sized accordingly to their percentage of global GDP output. Continents are also grouped together and sorted by color.
To create their map, The Eco Experts scrutinized data for 135 countries on carbon emissions, air pollution levels, and energy consumption, along with how much the countries draw on renewable energy. They also considered how many people have died from poor air quality. Bringing together all the individual rankings, The Eco Experts determined which countries are most damaging the environment and risking public health.

Guess what was found in Pennsylvania's Department of Environmental Protection's (DEP) filing cabinets after gas operators drilled 10,027 fracking wells over the last 12 years? Only 9,442 citizen-reported fracking complaints. And 44 percent of those are drinking water-related. Pennsylvania's DEP finally released the complaints to Public Herald, an investigative journalism nonprofit. There's much to learn from Pennsylvania's now-public 9,442 fracking complaints as legislators decide to frack or not to frack in Western Maryland.

Utilities across the country are trying to find ways to undermine rooftop solar, and some states are giving them some help. This month alone, Wyoming's legislature introduced a bill Opens a New Window. that would effectively ban both wind and solar in the state, including rooftop solar. Indiana's legislature is alsoconsidering a bill Opens a New Window. that would force rooftop solar owners to sell all of their energy production to the utility while buying all of their energy fr

China has announced plans to cancel more than 100 coal plants currently in development, scrapping what would amount to a massive 120 gigawatts (GW) of coal-fired electricity capacity if the plants were completed.
For a bit of context, the entire US has approximately 305 GW gigawatts of coal capacity in total, and this massive adjustment leaves room for China to advance its development of clean, renewable energy.
Electric utilities increasingly find themselves at war with their own customers. Homeowners and commercial building owners have all sorts of new choices for how to generate, store, and manage their own electricity — solar panels, home batteries, electric vehicles, smart thermostats and appliances, and more gizmos coming along every day.

When the D.C. Circuit Court of Appeals vacated FERC Order 745 by ruling demand response wasn’t tradable in wholesale energy markets, it left a vacuum of strategies to properly value and compensate demand response.
Today the U.S. Department of Energy's (DOE) Office of Energy Efficiency and Renewable Energy, with the White House Council on Environmental Quality (CEQ) and Office of Management and Budget (OMB), recognized 21 federal agencies during a White House event led by Christina Goldfuss, Managing Director of CEQ, and Shaun Donovan, Director of OMB. Over the last five years the agencies have awarded 340 projects, exceeding the President's Performance Contracting Challenge goal, which will reduce energy spending in the federal government by $8 billion over the next 18 years and create more than 30,000 jobs.

Ten years of effort finally paid off for Las Vegas this week when officials announced the city government will now be powered entirely by renewable energy. After a large solar array, Boulder Solar 1, came online on Dec. 12, the city was able to buy enough carbon-free electricity to power its 140 buildings, streetlights and other facilities. The power flows from a mix of solar panels and hydroelectric turbines including the Hoover Dam. The renewables, plus energy efficiency savings, are estimated to save the city roughly $5 million per year, reports the Las Vegas Review-Journal.

With an incoming presidential administration seemingly hostile towards action on climate change, local solutions are now more important than ever. With or without Donald Trump's help, the North Carolina municipality of Boone is calling on the whole state—and the United States at large—to encourage green jobs and transition to 100 percent clean energy across all energy sectors.
December 14, 2017
Playing around with the map, you can see why natural gas and renewables are likely to provide much of America’s new electric capacity going forward. It also shows why, despite Trump’s promises, it will be extremely difficult to build new US coal plants anytime soon. And you can explore the effects a carbon tax might have on America’s grid — or, say, the development of much cheaper nuclear reactors.
