Not exact matches

«But when you actually look at the total environmental impact,» he explains, «it takes three times as much energy to make that bag as we can use to make an equivalent polyethylene product.»

In India, for example, the average life expectancy is 301/2 years, compared to 681/2 years in the United States; the average annual income is less than $ 40, compared to $ 1,469 in the U.S. Energy utilized annually per capita, which is a rough index of living standard, is in some countries equivalent to.02 tons of coal, compared to 8 tons, or 400 times as much, in the U.S.. Two thirds of the world usually goes to bed hungry at night.

As I have argued, sheer single - minded operation on things — transforming walnuts into ice - cream topping, pepper - grass into impromptu salad — is not equivalent to full attentive engagement, however much energy it expends.

In the longer term, we need to fuel - poverty - proof older households through much more serious energy efficiency policies and programmes, such as Warm Front in England and its equivalents in other parts of the UK

Natural gas is by far the cleanest - burning fossil fuel, producing about half as much carbon dioxide as the energy - equivalent amount of coal.

This energy expenditure is much greater than the energy that a person wearing a backpack of an equivalent weight would use.

Electric motors are just much better at that transformation than internal combustion engines - which is why the somewhat wonky EPA conversion for MPGe (the electric equivalent of miles per gallon) shows a Volt getting like 119 miles per electric «gallon» worth of energy, and that conversion is actually pretty conservative.

He then goes on to make 1 J of electrical energy equivalent to 1 J of chemical energy, completely ignoring the much higher efficiency of electric motors compared to internal combustion engines.

I think I would also like figures for how much of that energy is acturally capturable at practical cost (say not more that 2X the equivalent nuclear generation).

In the body of the study it becomes clear that FCVs do not beat internal combustion engines (ICEs) by much in equivalent fuel economy, And they are not much better in greenhouse gas emissions either, particularly in the liquid hydrogen versions, because of the energy required to transport and compress the hydrogen.

Gas supplies equivalent to about 0.42 billion cubic feet per day could supply that energy, but both the Northeast Energy Direct and the Access Northeast Project proposals are much lenergy, but both the Northeast Energy Direct and the Access Northeast Project proposals are much lEnergy Direct and the Access Northeast Project proposals are much larger.

Even if natural gas combustion creates approaching 50 percent less CO2 equivalent per unit of energy produced, an amount which is well beyond best case on ghg emission reductions, it will not create the much greater emissions reductions necessary in the next 30 years to give any hope of limiting warming from exceeding levels that will cause catastrophic impacts.

At 15C this reverse step is in fact almost never going to occur due to the fact that all other energy transfer options are so much more likely and with much higher transition probabilities and that so few of the N2 molecules have energy significantly in excess of the equivalent of 15 um to overcome the impact parameter issues (i.e., most imapct parameters are going to be greater than 0).

That put the price equivalent at about $ 12 - $ 15 for as much energy as is contained in a barrel of oil as compared to over $ 100 for an actual barrel of oil today.

The argument is that if an electric vehicle is built through an energy - hungry manufacturing process it could actually end up generating as much CO2 as a petrol equivalent.

A Breakthrough analysis found that rebound effects as high as 60 percent (the IEA's high - end scenario) will have significant implications for global climate mitigation efforts, requiring as much as 13 percent more clean energy supply by 2035 to meet higher global energy demand — equivalent to the total energy consumption of 19 Australias.

How much do we have to change the average DLR value to provide an equivalent amount of energy over 24 hours?

Dozens of Titan's lakes individually have the equivalent of at least this much energy in the form of methane and ethane.

The combination gives much lower cost of equivalent energy (only ~ 10 - 20 % that of silicon technology).

First, more efficient appliances and automobiles cost much more to achieve equivalent energy savings than a tax on fossil fuel consumption.

Organics are processed at much lower temperatures than inorganics, and while their efficiencies are substantially lower (about 3 percent), they can be spread over wide areas, yielding an equivalent amount of energy.

The GE Reveal 60W Equivalent A19 Dimmable LED has a CRI score of 90, but it costs twice as much per bulb and uses more energy.
