Historical Perspectives of Energy Consumption

Increasing energy consumption ..

write a short essay detailing how energy consumption was …

Certain appliances and electronics consume a lot of energy. Reduce your consumption by using them wisely and in moderation and unplugging them when they are not in operation.

However, to properly address such an issue as over consumption of energy, one first must understand what “energy” is.

elements of the increasing energy consumption

Long ago I came to this conclusion, and to arrive at this result only two ways, as before indicated, appeared possible�either to turn to use the energy of the sun stored in the ambient medium, or to transmit, through the medium, the sun's energy to distant places from some locality where it was obtainable without consumption of material. At that time I at once rejected the latter method as entirely impracticable, and turned to examine the possibilities of the former.

But, whatever our resources of primary energy may be in the future, we must, to be rational, obtain it without consumption of any material.

Perhaps the most damaging deficiency in FE efforts, after self-serving orientation, was that the participants and their supporters were scientifically illiterate and easily led astray by the latest spectacle. Scientific literacy can help prevent most such distractions. While writing this essay, I was not only bombarded with news of the latest FE and alternative energy aspirants' antics, but I had to continually field queries regarding whether Peak Oil and Global Warming were conspiratorial elite hoaxes (or figments of the hyperactive imaginations of environmentalists and other activists), for two examples that readily come to mind. Digesting this essay's material should have those questions answered as mere side-effects. Far from being a hoax or imaginary, Peak Oil was and , and it is all downhill from there, and conventional oil will be almost entirely depleted in my lifetime. , although both were heavily promoted in the USA in 2014. In every paleoclimate study that I have seen, so-called greenhouse gases have always been considered the primary determinant of Earth's surface temperature (after the Sun), and carbon dioxide is chief among them. The radiation-trapping properties of carbon dioxide are not controversial in the slightest among scientists, and after the Sun's influence (which is exceedingly stable), declining carbon dioxide levels are considered to be the conditions that have dominated Earth for the past 35 million years. Humanity's increasing the atmosphere's carbon dioxide content is influencing the cause of Icehouse Earth, and , and are merely proximate causes. Increasing carbon dioxide can turn the global climate from an to a Greenhouse Earth, and the last time that happened, Earth had its . But have purposefully confused the issues, and a scientifically illiterate public and have played along, partly because believing the disinformation seems to relieve us all of any responsibility for our actions. Although scientific literacy can help people become immune to the disinformation and confusion arising from many corners, and reading this essay's first half can help people develop their own defense from such distractions, my goals for this essay's first half are far greater than that.

Essay on Energy Consumption in India


India’s per capita consumption of commercial energy, ..

The first graph is the case for nuclear. Only nuclear energy makes any dent at all in the world’s total energy consumption (about 22500 TWh of electricity in total was generated in the world in 2012, with more energy consumed directly as oil and gas). Although nuclear generation has dropped off significantly in the last year or two following the Fukushima accident, the experience of the 1970’s and 80’s shows that it is possible to add significant capacity in a reasonable timescale. Nuclear provides the world with a significant amount of low-carbon energy that it’s foolish to imagine can be quickly replaced by renewables.

Challenges of Meeting Increasing Energy Consumption with Clean ..

Construction of new affordable housing and helping “improve the quality and condition of affordable housing” are goals of the fund. This represents an opportunity to build new housing to net-zero energy ready standards (to which the federal government is steering all new construction by 2030). Net-zero energy ready homes use so little energy that they could generate the equivalent of their annual energy consumption with renewable sources, such as solar panels. Such low-carbon homes are more comfortable and durable, healthier, and more affordable to heat and maintain.

Linear Regression Analysis of Energy Consumption Data

The second graph is the case for solar. It is the same graph as the first one, but with a logarithmic axis (on this plot constant fractional growth shows up as an increasing straight-line). This shows that world solar energy consumption is increasing at a greater than exponential rate. For the last five years, solar energy consumption has been growing at a rate of 66% a year compounded. (Wind-power is also growing exponentially, but currently at a slower rate than solar). Although in absolute terms, solar energy is only now at the stage that nuclear was in 1971, its growth rate now is much higher than the maximum growth rate for nuclear in the period of its big build out, which was 30% a year compounded in the five years to 1975. And even before Fukushima, the growth in nuclear energy was stagnating, as new nuclear build only just kept up with the decommissioning of the first generation of nuclear plants. Looking at this graph, solar overtaking nuclear by 2020 doesn’t seem an unreasonable extrapolation.
