Do Renewables Lower Energy Consumption?

February 18, 2014 by Robert Wilson

Renewables and Energy Consumption

If a coal power plant is closed and replaced by a wind farm and that wind farm produces the same amount of electricity, what happens to energy consumption? Depending on the coal power plant, and how you define energy consumption it could do anything from stay the same to falling by a factor of three.[read more]

Sustainability: How Humans' Economy Differs from Natures'

November 5, 2013 by Gail Tverberg

Human Nature and Energy Consumption

A few years ago, I had an ah-ha moment when it comes to what we as humans would need to do to live in a sustainable manner. It is very easy. All we have to do is leave our homes, take off all of our clothes, and learn to live on the raw food we are able to gather with our own hands.[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]


Which Federal Regulations Can Best Reduce Petroleum Consumption and Carbon Emissions?

September 4, 2013 by John Miller

Regulation and Fuel Consumption

Many individuals advocate carbon taxes or cap-and-trade as the ultimate solution to reducing fossil fuels. Could the U.S. more effectively reduced its future petroleum consumption and associated carbon emissions by expanding existing regulations?[read more]

Whose Carbon is America Burning?

September 2, 2013 by Lindsay Wilson

American Carbon Consumption


In 2007 US carbon emissions peaked at roughly 6,029 Mt. We know a lot a how these emissions are generated, and why they have declined since then. But few of us who consume the carbon realize where the resources actually come from.[read more]


Are the Government’s International Energy Outlook Projections Too Conservative?

August 6, 2013 by John Miller

International Energy Outlook 2013

The EIA recently published a projection of future international energy balances, which indicates global fossil fuels consumption will continue to grow at substantially higher rates then renewables. Is this recent IEO 2013 analysis and forecast overly conservative?[read more]

Lowering Energy Consumption in Extreme Temperatures

July 11, 2013 by Sadhbh Ní Hógáin

Very low energy houses are better suited to cold climates; they consume 50% less than standard buildings and can be efficient, attractive alternatives to traditional housing, and can be achieved in cold climates through careful design.[read more]

Does Efficiency R&D Lead to Lower Energy Consumption? It's Complicated

July 3, 2013 by Max Luke

Efficiency Research and Consumption

Last week energy analyst Thomas Gerke wrote an article where he made an argument that research and development is an ancillary clean energy policy at best, and a distraction at worst. But it's much more complicated than that.[read more]

Oil Limits and Climate Change

May 28, 2013 by Gail Tverberg

future energy consumption?

If future energy consumption (which is mostly fossil fuel) drops because of a financial collapse brought on by high oil prices and other limits, then, at least in theory, climate change should be less of a problem.[read more]

The Close Tie Between Energy Consumption, Employment, and Recession

September 18, 2012 by Gail Tverberg

Since 1982, the number of people employed in the United States has tended to move in a similar pattern to the amount of energy consumed. When one increases (or decreases), the other tends to increase (or decrease). In numerical terms, R2 = .98.Figure 1. Employment is the total number employed at non-farm labor as reported by the US...[read more]

Getting Energy Communication Right for 7 Billion People

November 9, 2011 by Christine Hertzog

We marked a milestone on October 31, 2011 by hitting a human population total of 7 billion. Most of the world’s population lives in cities, and nations have been planning to make them as livable, sustainable, and resource-efficient as possible. For instance, China now has more than 220 cities that number over a million inhabitants. Contrast that to the USA, which has 9 cities and 41 urban counties that reach that mark, or Europe which has 35 such population centers. More than 100 Chinese cities including Beijing and Shanghai have signed on to projects to build smart cities – which leverage Information and Communications Technologies (ICT) to build egovernment infrastructures that deliver cost-effective and convenient services to citizens. Smart cities, like Smart Grids, are subsets of the Internet of Things (IoT), and China and Europe have much activity ongoing in forms of policy development, standards development, and actual pilots while the USA lags behind.[read more]

A smart electric network – in more ways than one

June 29, 2010 by Rich Maltzman

As we often do here on EarthPM, we are going to combine a couple of pertinent and important themes to hopefully strengthen some points that are key to each of them. The two themes we relate here are: Electric Smart Grids for effective power transmission and reduced carbon footprint High-powered Grids of Smart PMs to gain a bigger...[read more]

Information Privacy in the Smart Grid Age

February 8, 2010 by Christine Hertzog

New technologies challenge our ability to manage them.  Do you recall that many users of social networks like MySpace and Facebook were chagrined to discover that their personal information has achieved immortality on the Internet?  In many cases, users failed to appreciate the ramifications of their decisions about sharing...[read more]

OPower, peer pressure and climate change

January 19, 2010 by Marc Gunther

We can solve the climate crisis with the right tools–solar panels, wind turbines, electric car batteries, No. 10 envelopes and smiley faces. Envelopes? Smiley faces? Yep. A startup called OPower has learned that by mailing utility customers personalized reports on their energy consumption–and then by comparing them with their neighbors–...[read more]
