Therefore, the results presented here are inconsistent with the hypothesis of large reductions
in global energy consumption for outdoor lighting because of the introduction of solid - state lighting.
The overall impact of these changes
on global energy consumption will be relatively small although the impact on deforestation and food security may be considerable.
Renewable energy is making impressive gains in the electricity sector, although these are not being matched in transportation and heating — which together account for 80 %
of global energy consumption.
While the U.S. boom in shale gas helped push the fossil fuel's share of
total global energy consumption from 23.8 to 23.9 percent, coal also increased its share, from 29.7 to 29.9 percent, as demand for coal - fired electricity remained strong across much of the developing world, including China and India, and parts of Europe.
According to the IEA, implementing cost - effective energy efficiency measures in small and mid-sized entreprises could
reduce global energy consumption by 30 % — an amount equal to the total combined annual energy use of Japan and Korea.
Projections of total
global energy consumption show that between 2004 and 2030, fossil fuels will provide the bulk of the increase, with nuclear and other sources providing relatively minor contributions in absolute terms (Figure 3 and Table 1).
Without nuclear, the scientists
believe global energy consumption will overtake the planet's ability to reverse the buildup of carbon dioxide pollution from burning oil, coal and other fossil fuels.

The share of nuclear power, the other non-fossil energy source, remained constant at about 6 %, for many years, with nuclear capacity increasing in line with
increasing global energy consumption.
I would note that Alex Trembath's useful intervention to this discussion provides insight into why we can
expect global energy consumption will continue to grow, and tangentially why so much of that energy will be supplied by fossil fuels without an major breakthroughs in energy technology.
For instance, modern bioenergy in
final global energy consumption should increase four-fold by 2060 in the IEA's 2 °C scenario (2DS), which seeks to limit global average temperatures from rising more than 2 °C by 2100 to avoid some of the worst effects of climate change.
BP projects that global carbon dioxide emissions will rise by 29 percent by 2035 as part of a 41 percent overall increase
in global energy consumption — virtually all of it from developing economies.
The U.S. Department of Energy projects that
global energy consumption will increase by 53 % between 2008 and 2035, with most of that growth coming from the long - term economic expansion in Asian countries.
«If you look at this in a broad sense, about 5 percent of our total
global energy consumption is spent on electronics,» said co-senior author Ramamoorthy Ramesh, Berkeley Lab's Associate Laboratory Director for Energy Technologies and a UC Berkeley professor of materials science and engineering and of physics.
If these types of technologies were widely available on the market,
global energy consumption could be cut in half, said Piccard, speaking last week at the International Transport Forum summit in Leipzig, Germany, taking place concurrently with the Berlin Air Show.
On its current course,
global energy consumption would be 40 percent higher in 2030 than it is today.
According to the U.S. Energy Information Administration agency,
global energy consumption should rise nearly 60 % over the next 30 years.
