Global greenhouse gas emissions rise for the first time in 3 years

Emily Holbrook, ENERGY MANAGER TODAY

The International Energy Agency (IEA) announced today that greenhouse gas emissions rose 1.4% in 2017, marking the first rise in three years.

As the IEA points out, emissions have reached a historic high of 32.5 gigatonnes (Gt), a resumption of growth after three years of global emissions remaining flat. The increase in CO2emissions, however, was not universal. While most major economies saw a rise, some others experienced declines, including the United States, United Kingdom, Mexico and Japan. The biggest decline came from the United States, mainly because of higher deployment of renewables.

The report states, improvements in global energy efficiency slowed down in 2017. The rate of decline in global energy intensity, defined as the energy consumed per unit of economic output, slowed to only 1.6% in 2017, much lower than the 2.0% improvement seen in 2016.

The growth in global energy demand was concentrated in Asia, with China and India together representing more than 40% of the increase. Energy demand in all advanced economies contributed more than 20% of global energy demand growth, although their share in total energy use continued to fall. Notable growth was also registered in Southeast Asia (which accounted for 8% of global energy demand growth) and Africa (6%), although per capita energy use in these regions still remains well below the global average.

New greenhouse gas report highlights successes, challenges, and opportunities for Sonoma County and California

Ann Hancock, CENTER FOR CLIMATE PROTECTION

The Center for Climate Protection just released the new greenhouse gas (GHG) emissions report for Sonoma County for 2016. The good news is that emissions from electricity have gone down since the inception of Sonoma Clean Power, the region’s Community Choice Energy program. The reduction of emissions in electricity was so significant that Sonoma County’s overall GHG emissions were lower in 2016 than they were in 1990 even though the County’s population increased during this same period.

As other communities throughout California consider Community Choice Energy, Sonoma County’s GHG report offers them powerful proof that Community Choice Energy works to lower GHG emissions.

The report also reveals that Sonoma County, similar to other communities, is challenged to reduce emissions produced by transportation. This sector now accounts for about 70% of Sonoma County’s emissions.

How solarized is western and northern Sonoma?

Kyle Pennell, THE HEALDSBURG TRIBUNE

The level of solar penetration varies quite a bit between the cities and towns in western Sonoma County. At the highest level, 6.83 percent of homes in Sebastopol have installed solar. This is notably more than Healdsburg, where only 3.02 percent of residents have installed solar.

renewableHave you ever wondered how green western Sonoma County is and how we are contributing to protecting the environment and combating climate change? One major way we do this is by changing the way we produce electricity.

Household electricity consumption accounts for about one-third of all energy use, so by reducing or eliminating fossil fuels in electricity production, we can significantly reduce our carbon footprint as individuals and as part of the towns where we live.

Installing solar panels is the easiest and more effective way to make electricity more sustainable. We know that more western Sonoma County residents each year are installing solar panels on their rooftops.

But we were were curious — just how many rooftops have solar and how much electricity gets generated from them in Sebastopol, Windsor, Healdsburg, Cloverdale? If every rooftop in these four towns had solar panels, how much electricity would this generate? Finally, how much carbon emissions would be saved by all of this?

Marin County goes 100% green energy

Cynthia Sweeney, NORTH BAY BUSINESS JOURNAL

Government entities in the North Bay are leading the state with 100 percent renewable electric power.

In October, Marin County was the first in the state to enroll all of its county and city accounts in Marin Clean Energy’s 100 percent renewable electricity program, the company said.

Marin Clean Energy supplies customers with 50 percent to 100 percent renewable energy as an alternative to PG&E.

Called Deep Green, the program now supplies non-polluting wind and solar power for public buildings, streetlights and other civic accounts in the county.

The city and county of Napa also adopted the Deep Green Program in 2017.The city of Sonoma, and the Sonoma County Water Agency have also transitioned to Sonoma Clean Power’s 100 percent renewable energy program, called Evergreen.

Santa Rosa begins installing solar panels on parking garage roofs

Kevin McCallum, THE PRESS DEMOCRAT

Santa Rosa has begun installing nearly a thousand solar panels atop four city parking garages, modules that will both shade vehicles from the sun and reduce the city’s energy costs.

“I’m excited to see a much smaller PG&E bill,” said Luke Morse, the city’s parking supervisor as he helped organize the delivery of the panels on Tuesday.

A huge crane began hoisting the photovoltaic panels and the steel canopies that will support them onto garage roofs Tuesday morning.

If all goes well, the installations should take about a month per garage, with the project completed in a few months.

The city estimates the $1.4 million project will pay for itself in about 11 years and save $1.4 million in power costs over the 25-year life of the arrays.

That should help the city achieve about 10 percent of its 2020 greenhouse gas emission reduction target, said Kim Nadaeu, parking district manager.

Chile’s energy transformation is powered by wind, sun and volcanoes 

Ernesto Londoño, THE NEW YORK TIMES

Cerro Pabellón, Chile — It looks and functions much like an oil drilling rig. As it happens, several of the men in thick blue overalls and white helmets who operate the hulking machine once made a living pumping crude.

But now they are surrounded by snowcapped volcanoes, laboring to breathe up here at 14,760 feet above sea level as they draw steam from the earth at South America’s first geothermal energy plant.

With the ability to power roughly 165,000 homes, the new plant is yet another step in Chile’s clean energy transformation. This nation’s rapidly expanding clean energy grid, which includes vast solar fields and wind farms, is one of the most ambitious in a region that is decisively moving beyond fossil fuels.

Latin America already has the world’s cleanest electricity, having long relied on dams to generate a large share of its energy needs, according to the World Bank.

But even beyond those big hydropower projects, investment in renewable energy in Latin America has increased 11-fold since 2004, nearly double the global rate, according to a 2016 report by the International Renewable Energy Agency, an intergovernmental organization. Chile, Mexico and Brazil are now among the top 10 renewable energy markets in the world.

So as Latin America embraces greener energy sources, government officials and industry executives in the region have expressed a sense of confusion, even bewilderment, with the Trump administration’s decision to withdraw from the climate change commitments contained in the Paris Agreement, declare an end to the “war on coal” and take aim at American environmental regulations.

Climate group sees ‘inevitable’ shift to electric vehicles in Sonoma County

Guy Kovner, THE PRESS DEMOCRAT

EV report: Beyond combustion in Sonoma County

Meeting Sonoma County’s climate protection goals will require putting 138,000 electric vehicles on the road by 2030 and effectively ending sales of fuel-burning cars, a local environmental group said in a report due for release this week.

“We must now begin to create a future beyond combustion,” said the report by the Santa Rosa-based Center for Climate Protection.

Advocating a dramatic shift in consumer preferences and current automobile industry sales, the report said electric vehicle (EV) sales must grow by 30 percent a year for the next 13 years to meet the county’s goal for reducing greenhouse gas emissions.

Sonoma County has an estimated 4,500 EVs rolling now, the center said in its report, “Beyond Combustion: Electric Vehicle Trends, Goals and Recommendations for Sonoma County.

”Sales of plug-in hybrid and all-electric cars, both considered in the EV category, accounted for nearly 5 percent of the state’s new car market during the first three months of this year, according to the California New Car Dealers Association’s latest report.

EV sales have grown steadily from 2.5 percent of the market in 2013 to 3.6 percent last year, the association said.

Obsolete arguments against climate action

Dan Farber, LEGAL PLANET

Conservatives keep repeating the same arguments, even though the facts have changed.

There used to be some fairly plausible arguments against fighting climate change. I don’t mean crackpot theories about hoaxes or the “I’m not a scientist” hokum. Instead, the arguments I have in mind could be made with a straight face by serious people. I don’t think these arguments were ever truly persuasive, but they weren’t nuts.

You still hear a lot of these arguments today, often from conservatives claiming to take more nuanced positions on climate change. But these arguments have gone stale over time, as the facts on the ground have shifted.

Anyone who makes these arguments today just hasn’t done their homework. Here are these ghost arguments, which are living well past the time they should have gotten a decent burial.

“There’s too much uncertainty.” The IPCC’s first report 1990 expressed confidence that greenhouse gas emissions would cause global warming, but also found that warming up to that point had been within the range of normal variation. The most recent 2014 report – which is five times as long, reflecting a far larger body of research – found that warming had progressed to the point of being unmistakable, and well outside the range of natural variation: “Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, and sea level has risen.”

“China won’t act.” Chinese emissions rose exponentially along with its economy. China refused to agree even in principle to any caps on emissions. So it may have been a reasonable argument that U.S. action would be futile and would give China an unfair advantage. But that argument is well past its “sell by” date. In the Paris Agreement, China agreed to peak emissions by 2030 and committed to interim actions in the meantime. Change has proceeded more rapidly than expected, due to declining prices for renewables, efforts to curb deadly air pollution from coal use, and shifts in the Chinese economy away. In January, China cancelled plans to build over a hundred coal plants. It now seems possible that Chinese emissions have already peaked or will do so no later than 2025.

“Cap-and-trade will crush the economy.” California has had an emission trading system for five years. The economy has been growing and adding jobs over the same periods. The EU and the Northeastern states have their own, less ambitious trading programs. Again, no observable economic ill-effects.

“Renewables will break the grid.”  Since they depend on the weather, solar and wind are more variable as power sources than nuclear or fossil fuels. At one time, that looked like it might be a big problem – an issue that Rick Perry seems to be trying to resurrect. But this problem is looking a lot more manageable than it used to. California utilities are required to get 33% of their power from renewables. Somehow the lights have stayed on, day and night, regardless of weather. Germany has had a huge increase in renewables without causing any decrease in grid reliability. Better grid management is much of the reason, including demand response (paying selected users to reduce power use when necessary). These techniques have their limits, and we will probably need much greater energy storage capacity at some point when fossil fuels are pushed out of the generation mix. But even without technological improvements, electric cars offer an appealing combination of low-pollution transportation and energy storage capacity.

“Renewables are unaffordable.” The high price of renewables compared to cheap goal or natural gas seemed to pose a big obstacle to addressing climate change. The gap is much smaller today, and economic parity does not seem far away and may already have been arrived. According to a report from the World Economic Forum, Just ten years ago, generating electricity through solar cost about $600 per MWh, and it cost only $100 to generate the same amount of power through coal and natural gas. But the price of renewable sources of power plunged quickly – today it only costs around $100 to generate the same amount of electricity through solar and $50 through wind. Given the economics, it’s not surprising that in countries like India, where cost is a key consideration, more renewable capacity is being added to the grid than coal. I don’t want to exaggerate the ease of moving to a zero-carbon economy. There are still formidable difficulties – but they’re not as enormous as they looked a decade or two ago.

It’s convenient to continue believing in these arguments, especially if you’re worried about the risks of dissenting from your ideological soulmates. But ultimately, it’s the road to intellectual bankruptcy.In short, folks, it’s time to wake up and smell the coffee.

Rooftop solar dims under pressure from utility lobbyists

Hiroko Tabuchi, THE NEW YORK TIMES

Some of the slowdown in smaller-scale rooftop solar has come in maturing markets in states like California, where rooftop solar companies are having trouble expanding their customer base beyond early adopters.

Over the past six years, rooftop solar panel installations have seen explosive growth — as much as 900 percent by one estimate.

That growth has come to a shuddering stop this year, with a projected decline in new installations of 2 percent, according to projections from Bloomberg New Energy Finance.

A number of factors are driving the reversal, from saturation in markets like California to financial woes at several top solar panel makers.

But the decline has also coincided with a concerted and well-funded lobbying campaign by traditional utilities, which have been working in state capitals across the country to reverse incentives for homeowners to install solar panels.

Utilities argue that rules allowing private solar customers to sell excess power back to the grid at the retail price — a practice known as net metering — can be unfair to homeowners who do not want or cannot afford their own solar installations.

California grid operator calls for voluntary conservation during heat wave

ASSOCIATED PRESS

California ISO – See graphs for electricity supply and demand, renewable energy production and more: http://www.caiso.com/Pages/TodaysOutlook.aspx

The operator of California’s power grid has issued a so-called Flex Alert calling for voluntary electricity conservation between 2 p.m. and 9 p.m. on Tuesday and Wednesday, the expected peak of the current heat wave.

The California Independent System Operator says consumers shouldn’t use major appliances during those hours and should set air conditioners to 78 degrees or higher and turn off unnecessary lights to ease strain on the grid.

The forecast peak electricity usage is expected to exceed 47,000 megawatts each day.
