Human Population Through Time

It took 200,000 years for our human population to reach 1 billion—and only 200 years to reach 7 billion. But growth has begun slowing, as women have fewer babies on average. When will our global population peak? And how can we minimize our impact on Earth’s resources, even as we approach 11 billion?

This relates to our topic by showing that our population is growing rapidly. By the time 2025 there will be more than 11 billion people on the Earth. But we have enough resources to last us.

Analysis: How BP's energy outlook has changed after the Paris agreement

Analysis: How BP's energy outlook has changed after the Paris agreement | Sustainability Science | Scoop.it
Carbon Brief explores why the 2016 BP energy outlook appears impervious to the Paris climate agreement, the world's first universal, global commitment to cut emissions.

Garry Rogers's curator insight, February 12, 2016 12:08 PM

Instead of drastic cuts in CO2 emissions, BP predicts global emissions fall less than 3% by 2035.

Los Alamos lab contractor loses $57 million over nuclear waste accident

Los Alamos lab contractor loses $57 million over nuclear waste accident | Sustainability Science | Scoop.it
The contractor managing the nuclear weapons laboratory at Los Alamos, N.M., was slapped with a $57-million reduction in its fees for 2014, largely due to a costly nuclear waste accident last year.
PIRatE Lab's insight:

Absolutely amazing!  I never thought I would see the day when the department of energy would actually discipline nuclear contractors in any real way for performance failures.  Unbelievable.  Clearly a step in the right direction and a step to properly internalizing the externalities associated with fission-based weapons and power plants.

Should the U.S. Take Unilateral Action on Climate Policy?

Should the U.S. Take Unilateral Action on Climate Policy? | Sustainability Science | Scoop.it
Critics of unilateral action say the U.S. would pay too high an economic price without significantly moving the needle on climate change. Supporters say the goal is too important to wait.
PIRatE Lab's insight:

Wow.  I mean wow.  Read this opinions.  We solve everything so we therefore should do nothing?  

 

The argument that individual action won't move the needle is clothed in both an incorrect understanding of the facts AND a disregard of the actual map accompanying this article: there is an emerging patchwork of responses to carbon emissions simply because THERE IS NO UNITED APPROACH.  But the whole conversation is moving because of the northern Europes and Californias of the world.  They are showing the way.

 

I am sorry but the factually incorrect trope that job growth only comes from staying on dirty energy sources is pathetic and wrong.  Spoken like a person who 1) knows nothing about the energy industry 2) doesn't live along a low-lying coast, and 3) is ignorant of externalities.  

 

I have heard the same exact line from oil lobbyists about it being just "too costly right now" to ditch fossil fuels.  Representatives said the exact same words to my students a few weeks ago.  And those were the same EXACT words that I heard espoused in 1976.  Apparently 40 years has changed nothing and we can only stick to 1800s technology to power the world of the 21st century.  How fallacious and how pessimistic about our creativity and ingenuity.

 

 At the risk of an ad hominem attack, I don't think the author of such volumes as The False Promise of Green Energy and Creating Cayman as an Offshore Financial Center: Structure and Strategy since 1960 is the best expert the Wall Street Journal could have found to comment on the technical issues related to decarbonizing our energy infrastructure.

Are electric cars greener than traditional gas-powered cars? Depends on where you live.

Are electric cars greener than traditional gas-powered cars? Depends on where you live. | Sustainability Science | Scoop.it

Nowhere do automakers sell more hybrid vehicles than California, with its unique combination of environmental consciousness, high gas prices and traffic-choked highways.

But new hybrid models will be in short supply at this week's Los Angeles Auto Show — one sign that the technology is still struggling to break out of its green-car niche, experts say.

PIRatE Lab's insight:

There is nothing new about this analyses, but it is an updating of older efforts with the most recent numbers out there.  It is true that using coal-fired power to juice your your car is problematic, but for most of the county (e.g. coastal areas) most of us would be better off switching to electric transportation systems.  Also, the best possible solution is to power our vehicles with locally-generated power, such as roof top or garage-top solar panels.  

 

The trick is getting this into everyone's hands in an easy, turn-key manner.  I think the tone of this piece misses that key point.  This is an evolving conversation and new technology.  It also needs to be one part of a broad spectrum of approaches to de-carbonizing our energy markets.  Falling back onto the old mantra of "it doesn't work everywhere all the time" is a bit ho-hum and overly simplistic.  Kind of the way some folks feel it is necessary to write an op-ed about their research to get increased attention for it.

 

For those interested in the actual study, you can find it here:

There is also an interesting story, in a similar vein, from the LA Times about faltering gas-electric hybrid vehicles at this week's LA Auto show:

PIRatE Lab's insight:

Hmmmmmm....We are still having trouble figuring out where and how to store high level radiation waste?  It is almost like we started using a power source before we knew what to do with the inevitable aftermath and downstream consequences of the waste stream.  That's strange, I mean we would never do.....wait.  Never mind.

Ad Agency Designs And Makes Brochures Without Using Electricity

Ad Agency Designs And Makes Brochures Without Using Electricity | Sustainability Science | Scoop.it

The Leo Burnett agency in Lisbon was commissioned to create a brochure for the EDP Group’s Access to Energy (A2E) campaign, which aims to bring electricity to communities in Sub-Saharan Africa and the Amazon.
This campaign also sought to show that many developed countries waste electricity, so the creative team challenged themselves by designing a brochure without using any energy.
Paper was made, pressed and dried, and the two colors of the brochure were printed manually on the paper. The last step was perhaps the easiest—folding these brochures by hand.


Even the process was documented without electricity—film cameras were used, and the amount of effort put in can be seen in the video at the link.

PIRatE Lab's insight:

Cool demo, but the future is clearly not abandon electricity.  The pollution associated with the film camera world has a host of problems as well (mercury, etc.).  But I like the idea here and the notion of being able to do things outside of the widely accepted standards of production.

The Energy Numbers From 2014

The Energy Numbers From 2014 | Sustainability Science | Scoop.it

Sometimes energy makes headlines, sometimes it doesn’t. But it almost always has important implications for the global economy, the environment, and our day-to-day lives.

 

Here are ten energy statistics from 2014 that capture some of the most noteworthy trends of the year, and that will shape the energy world in the years to come.

PIRatE Lab's insight:

Some of these are obvious, but many of these were surprising to me.  None less so than the push to get California solar home arrays westward oriented to help with peak afternoon electricity demand.

How Weather Forecasts Can Help Optimize Energy Usage

How Weather Forecasts Can Help Optimize Energy Usage | Sustainability Science | Scoop.it

Researchers at the University of Adelaide have been exploring how using public weather forecast information can help deliver significant reductions in energy consumption.

 

Combining information from the Bureau of Meteorology with data from existing building management systems, the researchers have developed an intelligent model that remains one step ahead of the building’s temperature changes, automatically adjusting the heating and cooling supply accordingly.

Early experimental results have provided encouraging results, with at least 10 per cent energy savings shown to be possible.
