Burning BioMass is more Efficient than Creating Ethanol

What I just wrote up there is cialis samples obviously true. I mean, I am in no way surprised by that, but apparently it's a big story. I suppose the story, really, is that somebody actually got out a pen and purchase viagra paper and did the math.

Here are the results, "biomass converted into electricity produced 81 percent more transportation miles and 108 percent more emissions offsets compared to ethanol." Those are some good numbers, and I think we can all agree that, in an ideal world, we would all have electric vehicles.

Buuut, we don't. We have vehicles that run on liquid fuels, and a transportation and infrastructure that relies on liquid fuels. The average car in America stays on the road for ten years, meaning that, for quite a while anyway, we're stuck with liquid fuels.

Creating ethanol, by design, is less efficient than burning it for electricity. There are a half-dozen energy-intensive steps necessary to turn cellulose into ethanol. But ethanol is a more convenient fuel than electricity. We don't need advanced batteries, we've got the good choice levitra pharmacy pumping stations in place and there are already a lot of flex-fuel cars on the roads.

I hope we can all agree that electric cars would be better than ethanol-powered cars...but we should also agree that both are better than gasoline.

Half the story

One thing the author forgot to indian generic levitra mention:
In order to replace all internal combustion vehicles with electric vehicles we would have to almost double our current electrical generation capacity and revamp residential electrical infrastructure.

In order to charge the TESLA in 4 hrs it takes almost 75 amps at 240v. I believe in a conventional 110v household plug it takes closer to levitra viagra online 24hrs.

Remember where most of buy generic cialis online our current electrical comes from these days... COAL!!

Although I do agree that there is not one solution to our energy crisis and we will need all alternatives to fight foreign oil...
And there are plenty of tested electrici

Excellent point that electricity is cheaper to run cars than ethanol or gas. And just because we generate a ton of our electricity from buring petrolium and try it cialis on line coal doesn't mean there aren't proven alternatives. Look at Denmark, for example, where the renewable energy indusry has been active since the 1970s oil crisis spurred them as a nation to action. It's hard to swallow being so far behind a small country like Denmark, with such fundamentally important projects like renewable energy.

What about Biomass Thermal???? We as a society always desire the "sexier" more complex solution when sometimes easier, more logical ideas are bypassed due to perception and politics. Thermal energy consumes 1/3 of our energy in the viagra info U.S. and while a majority of it comes from clean natural gas, much of levitra online without prescription this could be utilized in higher value, mobile fuels when biomass could be used more efficiently, creating just as many jobs, more sustainably for thermal heating. The law of thermodynamics is order generic viagra on the side of this thought and we need to generic levitra fake look across the the Atlantic to our EU brethren as to their success.

yes, we do use liquid fuels. out of the question. And we can't just switch that easily from fuel to electricity either.
But to say ethanol is better than gasoline is not always true! that is the main problem. depending on the biomass source (corn, sugarcane, etc.), the region and scale of the production site, ethanol is not just a little worse than gasoline, but up to 30%!! so, I say, stop this nonsense, use gasoline and do something more efficient with your biomass!!
and it's even worse that this is subsidized from many governments (not just the US)
Not all green technologies are still green on levitra buy now the second look. Sad, but true.
I got a different answer
written by Max, May 13, 2009
I used publically available information and got a difference answer then the University group. If you don't assume any losses in transmission then, yes, electricity would be better. But around 90% of electricity is lost before being utilized. My calcs show cellulosic ethanol being 3X better on miles / dry tons (a proxy for acreage).

Let's not also forget that the economics of selling biomass-derived power are bad; it's only marginally profitable with subsidies. Selling liquid fuels is still a significantly better economic prospect.

The University and the canadian levitra Press must have missed all of this.

Ethanol has a lot in common with hydrogen. Takes a lot of energy to make it, and people appear to buy real viagra online be inhaling it, or something similar, which in turn creates delusions.

Nationwide, 49 percent of buy levitra over night shipping our electricity comes from coal. Here in Washington state, it's about 17 percent. In California, it's 15 percent. Washington and where to find cialis California have the highest per capita hybrid vehicle ownership rates so it stands to reason that electric vehicles purchase rates will also be highest here.

Switching to any new fuel source will involve massive infrastructure changes. However, electricity offers the cheapest new infrastructure costs. Electricity is already everywhere. We know how to make it, store it, transport it, and deliver it. Heck, with a vertical axis wind turbine or PV array you can make it yourself at home--cleanly and safely.

Ethanol hasn't really taken hold, and I'm not very hopeful about the promises of cellulosic ethanol. While I'm not opposed to biofuels, I support sustainable biofuels and oppose unsustainable biofuels. The way ethanol is made today, IMHO, is unsustainable.

In contrast, over the next 2-3 years, expect to see electric vehicles in dealer showrooms along with a parade of plugin hybrid vehicles.

Finally, EPRI studied the issue of plugin hybrids causing problems for the power grid. Short answer is they won't, and they will reduce greenhouse gas emissions even if the levitra in uk electricity recharging them comes from coal.
electricity - the way to go

@Max - something wrong with your sources if you have come to cialis 50mg the conclusion that 90% of electricity is lost before being used. Where is it being lost? How? Why hasn't anyone noticed it before?

Or are you just trying to sow a little confusion and doubt? Seems more likely.

First I'd like to say how sad it is that a story, on a site as prominent as ecogeek, entitled "Burning biomass is more efficient than making ethanol", carries a picture of a wildfire to illustrate the story.
Is this a deliberate attempt to mislead or does Ecogeek really not understand the difference between a wildfire and a biomass powered turbine?
Then I'd like to support the correspondent who says 90% of electricity is lost before it is used. Not very well phrased, but the sentiment is good. Coal-powered thermal generation is notoriously inefficient. Much of the energy contained in the coal is lost in escaped heat (some say as much as 66%) in the power station. Transmission losses account for a further 15% and inefficient appliances another 12% so I agree we waste a lot of energy through inefficient generation and use of electricity.
On the other hand, I disagree with the writer who claims that electrical consumption would have to double to accommodate electric vehicles.
Most of the charging would take place off-peak (overnight) when base-load power stations are idling and power is being dumped because it is not being used.
Rocky Mountain Institute's Smart Garage theory is worth a look in this regard.
Electric vehicles powered from renewable electricy generators would be a much better option than ethanol, but I still think biodiesel is the way forward for (drastically reduced) heavy and we use it order prescription viagra long distance transportation.
