Building and operating new wind energy can cost less than continuing to operate fully-depreciated conventional generation facilities
Wind energy has solidified its position as the most cost-effective source of new electricity generation, coming in now at less than one-third the price seen in 2009. The full “levelized cost” (LCOE)* for a megawatt-hour of onshore, utility-scale wind energy in the United States is now between US$29 and $56 on an unsubsidized basis, according to an authoritative analysis just released by U.S. investment firm Lazard.
Wind energy costs have dropped 69 per cent since 2009, and seven per cent just in the last year. In comparison, the key conventional energy sources of coal plants, natural gas combined cycle plants, and natural gas peaker plants have seen much more modest declines in the same period, while the LCOE of nuclear has actually increased.
Remarkably, the low-end of the wind energy cost range also falls within the range of operating costs alone for existing nuclear and coal generation. In other words, it can be less expensive to build and operate new wind generation than to continue to operate fully-depreciated conventional generation facilities. MORE
Cora Group’s new three-storey office building in Waterloo, Ont., is expected to be a template for other green office developments. Its operation results in no net release of carbon dioxide into the atmosphere. JENNIFER LEWINGTON/THE GLOBE AND MAIL
The project’s origins date to 2013 when Cora, with a history of clean technology in its projects, responded to an industry challenge from Sustainable Waterloo Region, a non-profit that works with local firms on climate change issues, to build an environmentally sustainable, multitenant office at market rates.
A key consideration, says SWR executive director Tova Davidson, was that the proposed office be replicable. “Creating one building does not change green building standards and organizational sustainability,” she says. “But if you can do one and it is scalable financially in a replicable model then you have a foundation to build something much bigger on.” MORE
At the end of 2016, Maersk had reduced carbon emissions by 42% per container and reduced their total amount of carbon emissions by 25%.
The world’s largest maritime shipping company has just announced that they are ditching fossil fuels in a bid for carbon neutrality – and they are challenging other companies to do the same.
According to the United Nations, oversea shipping contributes to roughly 3% of the world’s total carbon emissions while handling 90% of the world’s trading. Though phasing out fossil fuels will prove to be difficult, Danish-based shipping company Maersk plans to lead the shift towards sustainability by investing in renewable fuel sources and cleaner shipping models.
“The only possible way to achieve the so-much-needed decarbonization in our industry is by fully transforming to new carbon neutral fuels and supply chains,” says Søren Toft, Chief Operating Officer at Maersk. MORE

…But in the midst of these setbacks and outright tragedies, key leaders and movements across our country fought back with great ideas and even greater energy and resolve.
Movements such as “$15 and Fairness” and #MeToo and Black Lives Matter continued, in many places, to gain ground and ensured that out-dated and damaging attitudes were confronted.
Led by great progressive mayors in cities as varied as Vancouver, Saskatoon and Montreal, municipal councils took action to help their neediest citizens, including critical expansions of affordable housing.
The governments of British Columbia and Alberta, though divided on the issue of pipelines, continued to implement ambitious plans to create jobs including with First Nations, build critical infrastructure, and protect the rights of vulnerable communities, to name but a few of their accomplishments. Right before the holidays, BC announced its widely praised CleanBC plan — probably the most comprehensive Canadian attempt to date to achieve the transition to a low carbon economy. MORE
“It’s a paradigm shift from planning the city for cars to planning for people.”

LONDON — Horns blaring, tires screeching and miles of traffic — these are the hallmarks of busy cities the world over.
But that is changing in Europe as some urban areas take steps to regulate and reduce the number of cars as they aim to improve both the environment and quality of life.
Oslo is perhaps the furthest ahead with plans to restrict private cars within a half-mile radius of its city center. It expects to eliminate all 700 of its on-street parking spaces by the end of the year and is slowly closing streets across that area to traffic. MORE
(Reuters Health) – People who live in neighborhoods with more green spaces may have less stress, healthier blood vessels and a lower risk of heart attacks and strokes than residents of communities without many outdoor recreation areas, a small study suggests.

With the end of 2018 comes the near-certain reality that some critters, after millions of years of existence on Earth, are gone for good.
There’s little question that humanity’s continued exploitation of wild animals and the depletion of their habitats have left many species either clinging to existence, or at worst, extinct. Today’s extinctions are happening 100 to 1000 times faster than the expected, natural rate of die-offs. It’s grim. MORE
From pricing carbon to shifting diets, here’s what we need to prioritize now.
According to the Carbon Majors Database, 71 percent of global greenhouse gas emissions since 1988 can be traced back to just 100 fossil fuel companies. Hitting the 1.5°C or 2°C goals means these corporations, their customers, and other large enterprises must phase out fossil fuels (more aggressively than what Shell laid out in its vision for a zero-carbon world).
Governments will also have to come up with tax schemes to generate new revenue for investment in and incentives for renewable energy, reforestation, and carbon removal technologies. And we need to vote for leaders who will deliver on them. MORE
With a new, scary study appearing at what seems like once a week, good news on the climate front is always welcome. And in at least one climate-related way, the news in 2018 has been very good.
From Abita Springs, Louisiana, population 2,365, to San Diego, California, population 1.3 million, U.S. cities are joining others around the world in pledging to obtain 100 percent of their electricity from renewable (or at least non-carbon) sources. As of December 17, those are just two of the 102 U.S. cities that have made such a formal commitment. The mayors of those 102 cities and 104 others now stand with the 100 percent pledge, though more than half of them have yet to convince their governing bodies to follow their lead in the matter. Nineteen months ago, only 25 cities had made the commitment. In addition to these cities, 11 counties, Hawai’i and California are shooting for the 100 percent goal. MORE
Language is crucial to how we perceive the natural world. Help me to find better ways of describing nature and our relationships with it so we can better defend it

If Moses had promised the Israelites a land flowing with mammary secretions and insect vomit, would they have followed him into Canaan? Though this means milk and honey, I doubt it would have inspired them.
So why do we use such language to describe the natural wonders of the world? There are examples everywhere, but I will illustrate the problem with a few from the UK. On land, places in which nature is protected are called “sites of special scientific interest”. At sea, they are labelled “no-take zones” or “reference areas”. Had you set out to estrange people from the living world, you could scarcely have done better. MORE
