Nic Marks: The Happy Planet Index

Statistician Nic Marks asks why we measure a nation’s success by its productivity — instead of by the happiness and well-being of its people. He introduces the Happy Planet Index, which tracks national well-being against resource use (because a happy life doesn’t have to cost the earth). Which countries rank highest in the HPI? You might be surprised.

The Clean Energy Manifesto

Have you read  The Clean Energy Manifesto?

It comes from the summary of an ebook I wrote called Clean Energy Secrets for Homeowners.

The world's next resource conflict

BERLIN, Feb. 22 (UPI) — The next resource conflict could be about minerals and rare earth elements needed to fuel the green economy, as China, which supplies most of the minerals, is considering limiting exports.

There is great hope for a green boom to transform the CO2-heavy world economy into one that is less dependent on fossil fuels and more sustainable. Experts envision solar panels and wind turbines to produce clean power and heat and electric cars to cruise tomorrow’s roads.

The problem with these technologies is that they rely on minerals and rare earth elements, or REEs, which are produced by politically unpredictable countries, including China.

The market for REEs — needed for hybrid cars, wind turbines, solar panels and defense industry products such as missiles and radar systems — has tripled in size over the past decade.

Why not use hydrogen to fuel our cars?

Q: Is hydrogen an environmentally friendly fuel? Why not use hydrogen to fuel our cars?

A: An internal combustion engine does not use an oxygen tank, instead it uses air from the atmosphere free of charge. That air is 80% Nitrogen (N2) and 20% Oxygen (O2). When you combine hydrogen with “air” you generate water (H2O) and Nitrogen Oxide (NOx).

Most people don’t realize that when you run Nitrogen (N2) through the combustion chamber you end up generating Nitrogen Oxide (NOx), which is the precursor to smog.

If you want to improve urban air quality, hyrdrogen based fuel is probably moving in the wrong direction.

Other issues concerning the use of hydrogen fuel cells:

  • Safety.  In case of a collision the car must be able to maintain the safety of the hydrogen. This means the hydrogen fueled car must be built heavier which makes the car less fuel efficient.
  • Environmental impact of producing hydrogen. Hydrogen can be produced by two methods:
  • Electrolysis of water. Electricity can be used to split water molecules to create pure hydrogen and oxygen. Where does that electricity come from? Burning coal, usually.
  • Reforming Fossil Fuels. Oil and natural gas contain hydrocarbons (molecules that contain hydrogen and carbon) Hydrogen can be split off of the carbon. But when you remove hydrogen from a hydrocarbon you generate a byproduct called carbon dioxide. Generating hydrogen from fossil fuel does not make it a renewable or clean energy.
  • The environmental impact of an energy source requires us to consider the cradle to cradle life cycle of that energy source. It does not make sense to burn coal to generate electricity to produce hydrogen to fuel our cars. It does not make sense to use a limited supply of a dirt energy source to generate hydrogen. To be successful, the hydrogen economy must have a large supply of electricity to be used in separate hydrogen from water. The electricity MUST be generated from a clean energy source.

  • Cost. Hydrogen is NOT cheap.

As consumers we MUST all become technically literate AND participate in the discussions required to help form sensible policy.

We must consider the cradle to cradle life cycle of energy sources we use. The health and well being of our planet and our civilization depends upon it.

Build Renewable Energy NOW.

Our desire to live comfortably on this planet does NOT give us the right to kill the oceans.

Offshore drilling is killing the oceans.

Our survival depends on healthy oceans.

We need to replace dirty energy with clean energy.

The amount of work required to replace dirty energy with clean energy is HUGE.

The effort to become a clean energy planet requires that we create 11.5 TW of new non-carbon based energy in the next 25 years.

To generate this much new energy, we will need to retool our global economy.

In chapter 9 of the video lecture below titled “Climate Change Recalculated,” Saul Griffith proposes a plan for what it would take to retool the world energy production.

20% renewable energy by 2020

Raising the share of renewable energy from 8.5% to 20% in the overall energy consumption is a necessary contribution to the global fight against climate change and towards better control over our energy dependence. The various uses of renewable energy are examined: electricity through wind and hydraulic energies; electricity or heat through geothermal and solar energies; electricity, heat, and biofuel coming from biomass.
