If they seem unreasonable either too high or too lowwhat is the evidence that will dispute them? The analysis is intended to clarify a future energy supply scenario based purely on the situation as it now exists and the directions it shows obvious signs of taking.
Just as we saw with oil and gas, coal will exhibit an energy peak and decline, though for different reasons. As economies grow, so does their demand for electricity. The theory behind Peak Oil is widely available on the Internet, and some introductory references are given herehere and here.
I discovered in the process that crude oil production peaked in May and has shown no growth since then despite a doubling in price and a dramatic surge in exploration activity.
While that expectation may not be completely realistic, it seems close enough for the purpose of this exercise. Global Natural Gas Production, to One of the big concerns regarding a decrease in global natural gas supplies has to be about its role in the production of ammonia for fertilizer. The number actually Global energy supply mix 2050 renewables over 30 in a couple of years.
Of course the amount of additional uranium required will depend entirely on the number of new plants that actually get built. This similarity makes sense because oil and gas come from the same biological source and tend to be found in similar geological formations.
The differences between oil and gas have everything to do with the fact that oil is a viscous liquid while natural gas is, well, a gas. As in the case of nuclear power there will be pressures to speed up the development of wind power because of global warming and the depletion of oil and gas, as well as restraining forces imposed by economics, technical feasibility and perhaps some public resistance to having turbines in their neighborhood.
This change is a good thing, as it indicates that various regions will have a much wider range of energy options available to them than in the past. When we start producing oil from a region, we usually find and develop the biggest, most accessible oil fields first.
Electricity The energy we use can be broadly categorized into two classes, fuel and electricity. To resolve those situations I have relied on my own analysis and judgment.
Dams and generators last a long time. As one of these very large fields plays out it can require the development of hundreds of small fields to replace its production.
The net outcome is that in nuclear power will be supplying about the same amount of energy that it is today. Immediately replacing it with low-carbon alternatives can avoid more costly changes in the future.
As the gas supply declines the price will automatically rise and fertilizer prices will go along for the ride.
The longer and tighter we cling to our present ways, the more damage we will ultimately inflict on ourselves and the world we live in. In normal times the poor would appeal to the rest of the world for food aid. On the other hand, there is at least some basis for the projections beyond the enthusiasm of the proponents or the gainsaying of their detractors.
Europe and Asia are placing a lot of emphasis on electrifying inter-city rail and urban mass transit. As you can see from the graph in Figure 15 it matches perfectly with the projected trend of actual population growth over the last 20 years. One can also see excessive public optimism at work in the same field, where dreams of replacing the world's gasoline with ethanol and biodiesel are now struggling against the limits of low net energy in biological processes.
It has its share of problems, though they tend to be quite localized. Cogeneration CHP power stations use some of the heat that is otherwise wasted for use in buildings or in industrial processes.

I make no apology for this potential subjectivity; such scenarios always reflect the opinions of their authors, and it is best to be clear about that from the start.From – renewable energy grew at a rate higher than any other point in history, with a consumption increase of million tonnes of oil.
During this period, oil, coal, and natural gas continued to grow and had increases that were much higher than the increase in renewable energy. Renewable energy includes such sources as wind, photovoltaic and thermal solar, tidal and wave power, biomass etc.
Assessing their probable contributions to the future energy mix is one of the more difficult balancing acts encountered in the construction of the model. Power to double share of global energy demand by DNV GL report Renewables to account for 80% of production by mid-century as demand from EVs, buildings and manufacturing rises, according to second Energy Transition Outlook.
All in all, with a projected growth of % from now until it looks as though wind is the renewable energy source that will make the most difference to the world's energy mix over the next 50 years.
