Following the successful COP21 Paris agreement to limit GHG gases, the country must now convert the remaining 20 percent of it’s electrical grid to renewable energy.

This should be easy to do as 80 percent of primary energy generation is already renewable energy.

Maybe we just needed the will to act. Fortunately, COP21 has provided that impetus. [Ed.]

4 Simple Ways to Meet Our COP21 Targets

by John Brian Shannon | December 29, 2015

COP21: The Paris Agreement is nothing if it isn’t followed-up with concrete action to meet the new emission reduction targets

The COP21 Paris Agreement is the first time that many nations have declared their intent to actually do something in regards to global warming, instead of the vague expressions and hand-wringing that we’ve seen until Paris 2015.

One should rightfully expect that LEADERS from each nation will appear at future COP events to discuss their nations’ successes (and any legitimate failures) as they navigate towards their intended carbon targets.

1. Some nations will seek to meet their COP21 targets via greater ENERGY EFFICIENCY

And that of course, is the best ‘bang for the buck’ route with regards to energy use and CO2 reduction.

No matter how energy is produced, some amount of CO2 will be created. Therefore, each MegaWatt(MW) of energy that remains unused, results in zero CO2 emissions.

This can also be the case where a mixed grid employs clean, renewable energy.

Both solar and wind power feature zero emissions as standalone energy generators — however, in a mixed grid with various energy generators, from coal to nuclear, to gas-fired and biomass, and true renewables like hydro-electric, solar and wind — once all of the renewable energy capacity is exceeded, the other electricity generators must then ramp-up to match the total demand of those hours of the day.

See how utility companies choose the type of energy they use to meet electrical demand on a minute-by-minute basis: Merit Order – How Utility Companies Choose Energy

With increased energy efficiency, many MW of electricity will never be required in the first place, therefore, the need for non-renewable energy generation diminishes.

2. LEAVING COAL is the next best way to meet carbon reduction targets

Many people are unaware that natural gas burns up to 1,000,000 times cleaner than the dirtiest brown coal (lignite) and up to 10,000 times cleaner than the cleanest black coal (anthracite).

Non-CO2 Emissions caused by coal burning: Quite apart from Carbon Dioxide emissions, burning coal produces significant amounts of toxic airborne mercury and heavy metal vapours, and toxic gases such as sulfur dioxide, oxides of nitrogen and the lung-damaging particulates like smoke, ash, and soot.

Then there are the thousands of tons (Alberta only) or millions of tons (globally) of fly ash that must be transported and safely buried far from aquifers.

Obscene water usage levels are also a factor with coal use, as coal requires 1100 gallons of water per MW, while natural gas requires only 300 gallons per MW.

CO2 Emissions caused by coal burning: In regards to the Carbon-Dioxide-only component of airborne emissions, burning natural gas emits only 45% of the CO2 compared to coal on a per MW basis.

COP21 Coal-fired electricity generation in the U.S. is responsible for 80% of all U.S. emissions from all sources and causes millions of dollars of additional healthcare spending.

By simply converting every coal power plant in the world to natural gas, global CO2 and toxic airborne emissions would fall by many Gigatonnes.

I suggest that it’s an important enough goal that IMF, ADB, UNDP and UNEP money should be flowing to developing nations to help them convert to natural gas by 2020.

Yes, I said by 2020.

We’re either serious, or we’re enjoying our time at the COP confabs.

It’s time to actually accomplish something on the Earth Atmosphere file, instead of producing more sound bites.

Harvard University Medicine says that coal-fired power generation causes up to half a trillion dollars of damage annually to the U.S. economy. Maybe more. And that’s just in the U.S.A.

See: Harvard Medicine | Full Lifecycle Cost of Coal in the U.S.A.

3. Coal could be part of the solution instead of part of the problem – via significant investment in Coal-to-Liquid (CTL) fuels

Since 1955, South African gasoline (petrol) has been blended with super clean CTL fuel — which has a measurable and positive effect on vehicle emissions in the country.

The percentage of CTL to petrol has been rising over the decades as CTL capacity has increased. SASOL now blends a minimum of 30% CTL fuel into their petrol, which results in a very clean burn and lower engine maintenance.

Some South African airlines use clean CTL (coal oil) as a simple drop-in replacement for conventional petroleum (kerosene) fuel. Unlike conventional aviation fuel, CTL fuel is completely smokeless (and, bonus!) jet engines using CTL fuel require less maintenance.

CTL fuel blends reduce CO2 emissions for aircraft and cars and light trucks by 50% — and non-CO2 airborne emissions such as sulfur dioxide, oxides of nitrogen and particulate matter (smoke and soot) are virtually eliminated.

Thanks to the FISCHER-TROPSCH (catalytic) process, super clean-burning CTL fuels can be created from even the dirtiest brown coal.

4. We can’t have enough renewable energy capacity, especially now that it has attained price parity with conventional energy

See: The Falling Costs of Renewable Energy: No More Excuses (IRENA)

As a long term goal, we need to get to 50% renewable energy and 50% (any combination of natural gas and nuclear) for our primary energy generation in order to hit a reasonable CO2 target of 366PPM (the much advertised 350PPM CO2 target is noble, just that it’s utterly impossible to hit as long as there are 7 billion people on the planet) yet 366PPM is theoretically possible were all the stars were to align, and is a noble enough goal in itself.

Many nations have already hit their renewable energy targets, with some exceeding 90% of demand met by renewable energy.

Laos, Costa Rica, Kyrgyzstan, Tajikistan, Burundi, Ethiopia, Nepal, Democratic Republic of the Congo (DRC), Zambia, Mozambique, Iceland, Albania, Paraguay, Bhutan, Lesotho, Tokelau, all get more than 90% of their primary energy from renewable sources.

Some are now at, or very close to, 100% renewable energy. For instance, Costa Rica hit the 99% renewable energy mark this year. In 2016, Costa Rica is likely to become a renewable energy exporter.

Denmark produced 140% of its primary energy demand in 2015 with renewable energy. Some 40% of Denmark’s electricity was exported to neighbouring countries in exchange for for cold. hard, cash.

And Scotland hit its 2030 target (50% renewable energy) way back in 2014. At the rate Scotland is adding renewable energy to its main grid and microgids, it may reach 100% renewable energy before 2040.

So it can be done.

See: Ahead of Target: Scotland hits 50% Renewable Energy

See: List of Countries by Electricity Production From Renewable Source

SUMMARY: If we as a species, simply increase our total energy efficiency by 30% (a reasonable target) and legislate all coal-fired power generation to convert to natural gas by 2020 (merely accelerating what is already occurring due to market forces) and continue our present level of coal extraction for the purposes of creating super-clean CTL fuels, we would (by those changes alone) give ourselves an extra 15 years to find the best solutions to our pressing airborne emissions problem.

Again, the IMF, ADB, UNDP, UNEP, U.S. Dept of Energy, the EPA, COP21 sponsors, the World Bank and major corporations should be setting a good example with massive investment.

Finally, thanks to Bill Gates for his LEADERSHIP and PHILANTHROPY not only at COP21, but over the past decades — directly improving the lives of many people on this planet and supporting real and positive change in our shared global commons.

Our energy comes from many sources, including coal, natural gas, nuclear and renewables.

As nonrenewable sources such as coal diminish due to market forces and consumer preference, the need for renewable energy sources grows.

Some U.S. states satisfy their growing renewable energy needs with wind, solar and hydropower.

Wind: Texas has the capacity to generate 18,500 megawatts hours of electricity through wind, and expects to add another 5,000 megawatts of wind generation capacity from facilities under construction.

Solar: California’s solar farms and small-scale solar power systems have 14,000 megawatts of solar power generating capacity.

Hydroelectric: Washington state hydroelectric power produces two-thirds of its net electricity.
