At a time when the world needs to rapidly reduce greenhouse gas emissions, energy-related carbon emissions crept up 1.4 percent in 2017, according to a new International Energy Agency report. Fossil fuels met the bulk of new global energy demand, but renewable energy also grew.
The Arizona Senate passed a bill aiming to thwart a proposed constitutional amendment that would require half of the state's energy to come from renewables by 2030. The bill would require public utilities that violate the renewable energy standard to pay a fine of $100 to $5,000 — an amount so small critics say utilities could ignore the rules completely.
Pacific Gas & Electric says it will switch off power to minimize sparks in vulnerable areas during periods of extreme fire danger. State investigators are looking at whether the utility's equipment set off deadly wildfires last year. PG&E and other utilities have resisted preemptive power cutoffs in the past.
Hydrogen fuel cell cars are losing out against electric cars that run on batteries, and yet many auto industry executives are still pushing them as the way of the future.
Mexico is poised to increase its clean energy portfolio by 24 terawatt-hours by 2022, according to Bloomberg New Energy Finance. The country has a goal of 35 percent clean energy generation by 2024.

The Trump administration refused to accept European Union alternatives to tariffs on solar cells and modules, according to the World Trade Organization. The EU said its operations were not hurting the U.S. and asked for less penalizing alternatives.
New Mexico regulators approved a $1.6 billion plan by Xcel Energy to build two huge wind farms along the Texas-New Mexico border and to buy additional wind power from NextEra Energy Resources. Xcel says the three efforts will be able to power more than 440,000 homes.
Microsoft plans to buy 315 megawatts of power from a solar farm in Virginia that is expected to be the largest in the state and one of the largest on the East Coast, with more than 750,000 solar panels. The tech giant plans to use solar to power its data centers in Virginia.
Last year, Georgetown, Texas, shifted to all renewable energy. "We're doing this because it's good for our citizens," said Republican Mayor Dale Ross. "Cheaper electricity is better. Clean energy is better than fossil fuels."

The latest Energy Information Administration data shows a jump in wind and solar energy generation in 2017, while coal generation fell 2.5 percent from 2016 levels. For the first time in at least a decade, no new coal generation capacity opened.
After Hurricane Maria devastated Puerto Rico's power grid, a few bright spots were established on the islands where solar power systems were set up after the storm. But making renewables a mainstay will require more than solar panels and wind turbines.
Ten years ago, grid operators discovered the "duck curve": a peak in energy demand in the morning and another peak in the evening — but in between, there's a lag that gets bigger as more solar is added to the grid. As renewable energy come online, utilities are trying to figure out how to use energy storage make the grid more flexible.
Another rooftop solar company has entered the storage market: Sunnova, a solar financer, just launched its solar-plus-storage service in California. It's the latest shift as the residential energy storage market heats up.
Chattanooga, Tennessee, which has been a testbed for smart grid technology in the Southeast, is installing a solar-plus-storage microgrid at its airport in a project with Oak Ridge National Laboratory. The airport gets some of its power from a solar array, and the microgrid project will tie that to two 250 kilowatt batteries.

Vattenfall's winning zero-subsidy bid to build two 350 megawatt offshore wind farms follows a similar zero-subsidy tender in Germany last year, but the Dutch wind farms are expected to be completed first.
Maryland lawmakers have rejected two clean energy bills that would have expanded the state's Renewable Portfolio Standard and phased out fossil fuels by 2035. Lawmakers said they were worried about ratepayer costs and environmental impacts.
Solar industry stakeholders filed 55 comments to the Office of the U.S. Trade Representative looking for exclusions from Trump's solar tariff. One was U.S.-based SunPower, which says it will have to lay off employees and stop investments in U.S. solar manufacturing unless exclusions are approved.
Britain's wind farms generated a record 14.7 gigawatts of power last Saturday, representing 34 percent of the country's electricity generation. Britain plans to add 2 more gigawatts of wind farms this year as coal and nuclear plants retire.
By 2019, the University of Hawaii Maui College will be one of the first campuses in the U.S. to generate all of its energy from an on-site solar installation and battery storage. The entire university network plans to be 100 percent renewable by 2035, and the state plans to be by 2045.

Arizona utility regulators have instituted a nine-month moratorium on new gas plants larger than 150 megawatts. They are in the process of examining an overhaul to pursue 80 percent clean energy with a focus on energy storage.
Lithium, a key ingredient in rechargeable batteries, could be a lifeline for oil companies as they shift toward renewable energy and away from fossil fuels, an executive with an investment bank that advises energy companies says. Demand is projected to rise from 200 metric tons in 2016 to 7,845 metric tons per year by 2030.
While the remaining coal fleet faces pressure from natural gas and pending environmental regulations, the coal-friendly policies of the Trump Administration are giving it hope and younger, larger plants may be less likely to incur capital expenditures for refurbishments and upgrades.
In an effort to get Californians to stop driving as much and reduce emissions, a new bill would allow eight-story buildings near major transit stops, even if local communities object. The proposal, opposed by major environmental groups, points to a divide over how far the law should go to reshape urban lifestyles.
Thousands of entrepreneurs and inventors gathered at the ARPA-E Energy Innovation Summit last week to discuss new clean energy technologies, including wind turbine blades inspired by the leaves of palm trees, biofuel made from seaweed and new battery storage chemistries.

Last year marked the second straight year of double-digit growth in the solar industry, despite uncertainty around Trump's solar tariffs, according to an annual review from the Solar Energy Industries Association and GTM Research. But researchers forecast the U.S. will install less solar capacity in the coming years than previously expected.
The CEO of solar installer Sunrun sees U.S. utilities headed for a "huge spend cycle" on new poles and wires that's likely to raise electricity rates. That's going to give consumers another good reason to ditch the grid and install rooftop solar with batteries, she said.
A sharply divided Kentucky House of Representatives narrowly approved a controversial bill that could hurt the growth of rooftop solar. Some eastern Kentucky lawmakers joined their urban counterparts to vote against the bill, arguing that they saw it as a way to enrich utilities.
Bosnia, which generates 60 percent of its energy from coal-fired power plants, has started producing energy with its first wind power plant, a 50 megawatt project that can supply electricity to 27,500 households a year. The country wants to generate 43 percent of its energy from renewables by 2020.

If most vehicles and heat pumps were electrified, electricity demand could grow 2 percent a year through 2050, encouraging utilities to invest in new power sources just as renewable energy prices are falling. With the greening of the electric grid, the result would be significantly lower emissions, a new study says.
Florida Power & Light, the state's largest utility, has added a 40 megawatt-hour battery system to one of its solar projects, building what it believes to be the largest solar-plus-storage installation in the U.S. The utility plans to develop 50 megawatts of battery storage over the next several years.
