Mexico's Solar Energy Revolution

September 23, 2014 by Jacob Sandry

Mexico and Solar

In Mexico a growing population and an expanding middle class are driving energy demand to increase 4% per year. Mexico has a 60 GW energy demand, but that number will expand to 110 GW by 2024. And they want to solve this dreary problem with renewables.[read more]

Five Chinas & the Cartoon Guide to Climate Change

Growth and Carbon Emissions


In the past six weeks, Lindsey and I have biked across Turkey, talking to people about climate change. While a summary of our impressions can be found in this blog post, what struck us the most is how much new infrastructure, and especially power plants, Turkey is building.[read more]

Calling All Village Infrastructure Angels

Infrastructure and Energy

While it could potentially be clean energy's next big market, off grid clean tech suffers from an acute lack of finance. That's the real barrier to ramping up efforts to finally move 1.3 billion people around the whole world from darkness to light.[read more]

Rising Energy Costs Lead to Recession; Eventually Collapse

October 25, 2013 by Gail Tverberg

Population Growth and Energy

How does the world reach limits? This is a question that few dare to examine. My analysis suggests that these limits will come in a very different way than most have expected–through financial stress that ultimately relates to rising unit energy costs.[read more]

Population Growth: Addressing the Real Problem

October 2, 2013 by Robert Wilson

Population Growth

Getting people to produce fewer babies - they already are - is a far less important challenge than getting them to consume and produce energy more rationally. It is time we worried more about rich people driving luxury cars than poor people having more babies.[read more]

Population Growth: Malthus Rolls Over

July 7, 2013 by Sieren Ernst

Oxford Computer Science Professor Steven Emmott published an excerpt of his book, 'Ten Billion.' His excerpt breaks all of the rules about communication on environmental issues. It uniformly grim and offers no solutions.[read more]

Population Growth and Pollution: the Facts Continue to be Ignored

July 2, 2013 by Robert Wilson

Population Growth

Population growth is often referred to as the elephant in the room, but the facts indicate that the population bomb is being defused, and that continued worries are a deflection of the cause of a problem away from those who have caused it.[read more]

What Would it Take to Get to a Steady State Economy?

May 17, 2013 by Gail Tverberg

We seem to be headed for collapse, because humans’ growth is so far out of line in relationship to that of other species. In addition, there are many other limits, including the cost of oil extraction and availability of fresh water.[read more]

The Price of Ignoring Energy Innovation

what of future energy needs?


If carbon dioxide levels in the atmosphere are to stop increasing, then nearly all of oue future energy consumption must come from technologies that produce zero emissions.[read more]

Reaching Energy Limits in a Finite World

May 7, 2013 by Gail Tverberg

Our financial system has been built assuming that economic growth will continue indefinitely. There is significant risk that the recessionary influences of high oil costs will bring down the current economy.[read more]

How Energy Shapes the Economy

September 4, 2012 by Gail Tverberg

Researchers have found an extremely important role for energy. The relationship they have found relates to any species, not just to homo sapiens. Ecologists often talk about the existence of a natural cycle between predators and prey. The predators eat the prey that is available, but in time, the predators drop in number, as less food becomes available.[read more]

Rentier Debt and the Collapse of Debt-Based Finance

June 11, 2012 by Gail Tverberg

At the Age of Limits conference near Artemis, Pennsylvania on May 25-28, I was asked to speak on rentier debt and the collapse of debt-based finance. This is a somewhat difficult subject, so I decided to talk about the subject more generally–how growing debt fits in with economic growth and growth of energy supplies, and how inability to...[read more]

Is Economic Contraction a Climate Solution ?

January 24, 2012 by Matthew Stepp

Matthew Stepp and Jesse Jenkins examine whether voluntary economic contraction is a key strategy in reducing emissions “as quickly as possible.” What do you think?[read more]

Infinite Growth and the Crisis Cocktail - Guest Posting

December 18, 2010 by Michael Tobis

This is a guest posting by Neven. I made no changes except for adding the hamster movie in among the references. I don't necessarily agree with every word, but this definitely seems to get at the root of the problem. --mtThe Crisis CocktailIf only Thomas Robert Malthus would have been around to see this, I often think. During his...[read more]

Consumption dwarfs population as main global warming threat

April 13, 2009 by Joseph Romm

A number of commenters suggested I write about population and global warming (see here). Leading environmental journalist Fred Pearce beat me to the punch with an excellent piece at Yale’s e360 that I almost entirely agree with. Pierce’s key point is that the rapacious consumption of hydrocarbons and other non-renewable resources...[read more]
