Shale, Not Renewable Energy, Is Reducing Carbon Dioxide Emissions

Energy Research


The facts are the facts and it’s shale, not renewable energy, that’s allowing the U.S. to reduce carbon dioxide emissions while others merely yap about it.

Carbon dioxide emissions, the largest component of greenhouse gases, have been declining in the United States, mainly due to the shale gas renaissance. Between 2005 and 2016, U.S. carbon dioxide emissions declined by 12 percent. However, China’s carbon dioxide emissions over the same period increased by 50 percent, surpassing U.S. carbon dioxide emissions in 2006.

China’s commitment to the Paris Agreement is to allow greenhouse gas emissions to continue to rise until 2030, when they are expected to peak. China’s emissions are projected to rise approximately 3.5 percent this year due partly to poor hydroelectric output. While China’s emissions are allowed to increase, the Obama administration pledged that the United States would reduce its greenhouse gas emissions 26 to 28 percent below 2005 levels by 2025.

India, the world’s third largest emitter of greenhouse gases, pledged to install more renewable energy and to lower its carbon intensity—the amount of CO2 emitted per unit of gross domestic product. It will do so while allowing total emissions to increase through 2030, similar to China. India’s carbon dioxide emissions are expected to increase 2 percent this year—slower than the 6 percent annual growth seen over the last decade. India still has 240 million citizens without electricity and needs to provide reliable power to them.

Carbon dioxide emissions worldwide are increasing as the graph below shows, though their rate of growth has slowed in recent years. That may be temporary because global carbon dioxide emissions are expected to increase by 2 percent this year. Global carbon dioxide emissions are continuing to grow despite investment in renewable energy.

Over the past 10 years, governments and private investors have together spent $2 trillion on infrastructure to produce electricity from wind and solar power. According to Environmental Progress, after adjusting for inflation, that level of investment exceeds the total cost of all nuclear plants built or under construction. In recent years, renewable capacity has outpaced all other sources—including coal, natural gas and nuclear power. Solar and wind capacity installed in 2015 was more than 10 times what the International Energy Agency had forecast a decade before.

However, as seen from the graph above, this investment in wind and solar capacity has not brought about much decarbonization. Integrating renewable energy into the grid requires large investments in electricity transmission—to move power from intermittently windy and sunny places to places where power is consumed. It also requires fossil fuel plants to be ready to operate when there is no wind or sun. These back-up plants operate at levels far below their maximum capacity, increasing their operating costs and making them uneconomic.

Further, these intermittent renewable sources can drive wholesale electricity prices down to the point where they force back-up power off the grid. There are times when intermittent renewable generators flood the grid with power, reducing the price of electricity to negative levels due to tax credits, thereby forcing back-up power off the grid. Or, if the back-up power cannot shut down quickly, it must pay for the grid to accept its electricity.

German electric prices have skyrocketed as grid is plunged into turmoil by renewable energy political correctness

Despite some countries making progress in integrating wind and solar energy into their electricity mix, their carbon dioxide emissions have actually increased. Germany, for example, is now generating 34 percent of its power from non-carbon sources (hydro, nuclear, wind and solar), but its carbon dioxide emissions have increased in the last two years as the country is closing nuclear plants and backing up its intermittent renewables with coal. Germany’s residential electricity prices have skyrocketed to pay for the new renewable capacity and are three times those in the United States.

The United States is ahead of many countries in reducing its carbon dioxide emissions. That result is largely because of increased generation from inexpensive natural gas rather than from constructing wind and solar generators that produce much less energy per unit of capacity.

  1. If the promoters of wind turbines and solar panels actually admitted to the negative environmental impacts those industries are responsible for, the conversation would be a lot different.

  2. Ms Orlando. If natural gas has no benefit then explain to me why 5,000+ largebuildings in the NYC area switched from fuel oil to natural gas?? Better yet, why didn’t these 5,000+ large buildings go solar and or wind?? It would seem perfectly logical to have maximum impact in the most densely populated area of the USA for wind an or solar to be installed. Please explain why this isn’t being done? As a side note what is the heat source for your residence(s)?

  3. Three comments:

    1. You are focusing on carbon dioxide. What about methane? That is a more powerful greenhouse gas that leaks into the atmosphere from NG installations.

    2. No matter how you try to spin it, wind and solar do not emit greenhouse gases. Burning natural gas does. I really wish that NGN would look upon those renewables in a more favorable light. Your blog comes across as cheerleading for natural gas – and ONLY natural gas. There is room for other ways to produce electricity – right? Don’t be so narrowly focused. After all, many energy companies themselves are diversified.

    3. Energy storage technologies are still under development. Maturation of those technologies over the next decade will help us better deal with temporary energy gluts, when they occur.

  4. A different perspective.
