Strong global demand for energy surpasses the growth of "clean"

Strong global demand for energy surpasses the growth of "clean"



"The world demand for energy is surpassing the powerful growth in renewable energy and energy efficiency," says Stanford University professor Rob Jackson to Efe about the increase in global carbon dioxide emissions in 2018.

It is the second year in a row that the emissions of one of the gases causing the "greenhouse effect" have grown, but even so, Jackson, a senior professor and senior member of the Stanford Precourt Energy Institute, does not lose hope that clean energies will impose on everyone.

According to the report entitled "Global energy growth is surpassing decarbonisation", published this week in Environmental Research Letters and in Earth System Science Data, global emissions from fossil fuels will increase by 2.7% in 2018. relation to 2017.

The study has been prepared by the Global Coal Project, in which Stanford University (California) participates.

The year 2018 will end with a little more than 37,000 million tons of emissions from fossil sources to which 4,500 million non-fossil sources, such as deforestation, will be added.

Jackson points out that "the use of clean resources" is not happening anywhere in the world equally and that it is economic reasons that prevent some of the large Asian countries from leaving aside the most polluting energy sources, which has had an impact on the increase of emissions.

The report mentions that China has resumed coal-based projects that were suspended and in India, in the face of widespread poverty and a huge population, coal remains the most widely used energy source.

But, in addition, "in the United States a 2.5% growth in carbon dioxide emissions is projected in 2018 after a decade of decline", according to the report.

Jackson notes that "the first thing that China can do is reduce the use of coal, especially by pollution factors, and replace it with clean and renewable energy resources."

In India, "where poverty is the biggest concern" the expert says that there are "millions of people who lack electricity and have to use coal" and that they can not be blamed for it, says Jackson.

In the United States, according to the study, colder winters in eastern states and hotter summers in many states, "increased seasonal energy needs for heating and cooling."

Likewise, "a growing appetite" for gasoline in the face of falling prices helped the increase in carbon dioxide emissions in the country.

"We are driving more miles with bigger cars and they are changes that are surpassing the improvement in vehicle fuel efficiency," Jackson said.

In the opinion of this university professor, it is in the electric sector where "coal and natural gas can be more easily replaced by less polluting sources".

However, in the transport and automotive sector "is where it is more difficult to generate change, so we must focus a special effort towards that field".

A good news of the report is that the use of coal has not continued to rise in the United States and Canada, where it has decreased by 40% since 2005.

"The strength of the market and the interest in cleaner air are pushing countries toward natural gas, wind and solar energy," as energy sources, the scientist said.

The work now focuses on replacing oil and natural gas with renewable sources, as is happening with coal.

Although the researchers anticipate that in 2019 the carbon dioxide emissions will continue their growth, Jackson maintains his optimism.

"I think we will continue to carry out the transformation so that – especially electricity – continues its increased use of less polluting energy resources," concluded the Stanford researcher.
