perpetual_motionThis post examines the central role of energy in our lives by posing the hypothetical question the impact that free and unlimited energy would likely have on our world. Of course, as the author points out energy is neither free nor is it unlimited and prices for fossil fuels are destined to rise as emerging economies energy appetites make themselves felt on the market. From a venture capital perspective, it is this type of disruption that makes cleantech a compelling area for investment.

As soon as gas prices rise, our nation becomes focused on energy. When they drop again, it falls off most consumers’ radar. Yet the importance of energy goes way beyond the cost of filling up your gas tank or paying your electric bill. In often-extraordinary ways, energy is interwoven into absolutely everything that we need to live or that we love to do. One of the most useful tricks I learned in engineering school is that to put any problem in perspective, it helps to ask what if things were at zero or infinity. So, to put things in perspective, let’s ask the question…

“What if energy were free and unlimited?”


People would be able to travel at bargain-basement rates. Yes, the cost of land vehicle transportation, which is so much of the focus in the press, would drop by 25%-35%[i]. But, in addition, airline costs would plummet as much as 50%. With this would come increased commerce and maybe even greater worldly understanding, as more people are able to travel.

The world’s growing shortage of fresh water would largely disappear. A huge amount of energy is expended on the conveyance, pre-treatment, distribution and wastewater treatment. Energy represents 30% or more of a typical municipal water facility’s expenses.[ii] With free energy, water could affordably be produced in abundance through the highly energy-intensive processes of desalination, wastewater purification or even direct extraction of water out of the air.

Few in the world would go hungry. Today, energy represents roughly 30-45%[iii] of the cost of the food we put in our mouths. Farming, transporting, processing, packaging and retailing all consume tremendous amounts of energy. The price of food would drop and the availability of food would skyrocket. With free and unlimited energy, food could be grown affordably just about anywhere, given that water would be readily available and, where necessary, climate-controlled growing facilities would become inexpensive to operate.

Economic prosperity would reign. The correlation between energy consumption and standard of living is strong.[iv] Everything that we use consumes energy to be produced and transported. For example, energy represents roughly 50% of ocean shipping cost and 40% of aluminum production cost. Impoverished people would have more food to eat and cleaner water, their homes would become more comfortable, and the price of almost everything they buy would go down instantly, boosting their quality of life.

standard of living

The above graph is from the United Nations Development Program (UNDP) – 2004 World Energy Assessment. The horizontal axis shows per capita energy consumption by country, while the vertical axis shows each country’s UN Human Development Index rating.

So, the next time you hear complaints about high gas prices for our cars, remember that energy affects much more than just the cost of your ride to work or trip to the beach. With this perspective in mind, it doesn’t take much to figure out what things would look like in the opposite scenario, where energy becomes extremely expensive and scarce as fossil fuels diminish. It isn’t a matter of whether we will move away from fossil fuel consumption; it’s a matter of over what time period and with how much economic, national security and environmental pain along the way.

Check out our related post: “Unpredictable Oil Prices are Hurting Everyone“, to read how the wild price swings in the oil markets, moving from successive new price peaks to subsequent price collapses as the global economy goes into recession, are damaging the global economy and making it harder to raise capital for long term energy solutions.

The free market will most assuredly create more alternatives as energy prices rise. If we could be confident that future increases in energy prices would be gradual over a long period of time and that global warming was not a concern, there would be little reason to take any particular action. But history has already shown us that changes in fuel prices are unlikely to be gradual. And the growing industrialization of major portions of the world such as China and India mean that world energy consumption is likely to grow roughly 50% over the next 20 years.

This leaves little doubt about the direction of energy prices in a world dependent mostly on fossil fuels. From a venture capital perspective, it is this type of disruption that makes cleantech a compelling area for investment. From a policy perspective, if we are faced with high energy prices for an extended period of time or if global warming creates environmental chaos, the negative impacts could be extraordinary and would impact virtually every part of our lives. But, on the positive side, an expensive gas tank fill up would soon be the least of our concerns!

    Hi David,

    I have been preaching the same thing you are writing about for about 4 years now. The solution, to so many things on our planet, is to embrace the change to a free energy economy, which will result in all of the benefits you pointed out.

    I am the executive director for the Florida Keys Environmental Coalition ( and am intertwined in many profitable eco-projects. While there is no panacea at this time to instantly provide truly deployable energy systems that would address the rural and urban needs of our planet, there should be a visionary understanding that this is the true goal.

    The resistance of fuel production companies is probably one of the biggest hurdle, along with manufacturing companies that would rather believe that profit comes easier by producing minor evolutionary changes in their product line, than actual developing a completely new effectively free set of technologies. They all fear they will work themselves out of a job, or corporate profitability in this case.

    Oh contraire! There would still be plenty of work in system production and maintenance. In-fact potentially more than they do now, given they would be serving a much higher percentage of the world population with energy systems.

    I just wanted to say I appreciate a like mind with a bigger voice!

    Hi David and Barry
    The problem to finding a true replacement for crude oil, lies more in the attitude of investors and government than in what is available.
    I know of a team of engineers and inventors who worked for 8 years and tackled every single problem associated with creating diesel from algae at 35 cents a gallon. They took their work to VCs, angels and Governments and the only people who responded instantly and offered them the $7.6 million that was need to build a fuel factory connected to a generator was the Chinese.
    Without exception everyone else said it was too early stage, or needed more work or perhaps a bid for an EU or DARPA grant “might” be succesful.
    Chinese officials read the summary and said this changes the world and 24 hours later the team were offered a trip to Shanghai, facilities and all the money they needed.
    They have not accepted yet, but in their hearts know this is the only intelligent analysis that they will encounter.
    What is needed is better and quicker anylists who can see past the “early stage” formula and see the strategic value of real new technology

    A complete and total collapse of the world as we know it. No one would work since money is no longer a factor. As a result, nothing would be made. People would just fight over what already exists since no more new product would be created.
