It's highly unlikely that within "our" lifetime we will completely run out of oil. What is likely to happen is that oil prices will continue to rise, until it gets to the point where it's economically advantageous to invest more significantly in alternatives. Why we're not going to run out of oil (soon)... When we talk about how much oil is "left", we're ...

As Highly Irregular suggests this very much depends on the specifics of your vehicle, conditions outside of your car and your desired conditions inside your vehicle. When this question was brought up on skeptics the best evidence we could find was from Mythbusters which visited this topic in both episode 22 and episode 38: Episide 22 PARTLY CONFIRMED * ...

It's a more complicated answer that just saying "use your air con if you're going over X km/h". When it comes to keeping cool in your car, there are other factors that make a big difference: On a cold but sunny day, the inside of a car can still get very hot, but opening a window just a little bit can reduce the temp to a comfortable level and is unlikely ...

This only addresses part of your question, but this question could be answered with a whole book. Homebrewing Biodiesel I do want to clarify that biodiesel is not only a potential "industrial" reuse for used cooking oils. Used cooking oil can be processed into biodiesel by a modestly savvy do-it-yourselfer at home, with a simple processor that you can ...

It doesn't. Assuming you're referring to wind capacity additions, it most closely tracks the political winds in the U.S., in the form of the Production Tax Credit (PTC), a federal incentive program for construction of new wind capacity. The U.S. Department of Energy's Wind Vision report makes this relationship clear: This chart ends at 2013 when the ...

You can compost the oil / grease if you have the room. It's just not as easy to do as most kitchen waste. Oil tends to make your compost pile anaerobic, so its gets smelly and can attract vermin. But if you have the space for a second (or more) composter / compost pile, and can control the vermin, it will work. Since the pile will likely be anaerobic, just ...

There are two issues with used motor oil. One is that PCAH forms Thats Poly cyclic aromatic hydrocarbons. Benzene like rings with odds and ends attached. Many are biologically active, some are carcinogenic. If burned at high temp, with sufficient oxygen, they aren't a problem. Incompletely burned they are serious problems. The second issue are the very ...

Commercial/ Factory designs have been replacing the power transmission of "lubricated chains" and "gear mechanisms" with high performance "Timing Belts" made of special polymer composited with steel fibre etc. One of our family was extensively involved in such redesigns/ solutions in all possible industries beyond automotive that you can think of (hydro ...

First of all you are picking up pennies while the world is burning bills. The amount of oil from your chain is small even compared to the amount of oil that comes out of your exhaust, which in turn is small compared to the unburned hydrocarbons from the gasoline, which in turn is small compared to what everyone in their SUV's are releasing. You are already ...

If you just changed the oil, ground cork or sawdust works well. If the oil has been sitting there then try distilled white vinegar with baking soda. Take a shop broom or large brush with hard bristles and put some muscle into it. It may take a few rounds.

I did some digging and found data with a bit more resolution. First, polysilicon prices since 2010: Source: Fu, et al, Economic Measurements of Polysilicon for the Photovoltaic Industry: Market Competition and Manufacturing Competitiveness. Then, crude oil prices since 2010: Source: www.macrotrends.net, Crude Oil Prices - 70 Year Historical Chart. Note ...

No. As the graphs provided show, the prices both spike during the GFC, loosely speaking, but the oil price spikes later and declines faster, then continues a general slow rise while the price of silicon falls. Note that in late 2005/early 2006 oil drops abruptly while silicon is rising sharply, but during the 2011 blip in silicon prices you see a similar ...

While you have dismissed it in your question, I'd say that the best way to dispose of old oil is to convert it to Bio-Diesel and burn it - that reduces the amount of conventional Diesel that is dug from the ground, or made from virgin plant oil (which has the associated issues of using fertile ground for fuel instead of food). Oil-fuelled vehicles are going ...

TL, DR Solar thermal with a gas burner for peak demand. Possibly improved isolation. First, you need exact data on how much heat you need, and when, during the year and during each day. This should help you get an idea if the insulation of your house can be improved. Once you have the numbers, ask here for a first orientation. Without seeing the house (...

Biogas This is not for DIY (as far as I know), but I know that it can be turned into biogas through fermentation. In my city (Zurich, Switzerland) food scraps are collected and they specifically request for fats and cooking oil (also liquid ones soaked up by a paper towel). Of course it's up to debate how sustainable that is.

The problem is not the pipeline itself. Large pipelines are standard engineering. The disruption is fairly short term. The problem is that it would make a ready market for Canadian Oilsand oil to get to the gulf coast refineries. This drops the price of oil on a long range basis. (The Athabasca tar sands have more oil in them than ALL of the known ...

Here's a quick answer; hopefully we'll see some more in depth answers too. Looking at the given charts closely, the price of polysilicon appears to decline from around $75 in early 2010 to $17 in 2014, but the price of oil appears to gradually rise from $80 to $100 over the same period. This is very different behaviour, and says to me the relationship ...

You could definitely switch to an efficient gas boiler system with proper controls to run "cleaner" and more efficiently. Depending on gas/oil prices in your area, this may or may not be economically beneficial (short or long term). Varying with your current setup, electrical prices in your area (and their generation method) you could also change about ...

I'm going to be politically incorrect and say yes. "The solution to pollution is dilutions" Toxicity is in the dose. The amount of heavy metals and PAH's (Polycyclic aromatic hydrocarbons) is significant. This is likely causing the anti-termite effect. A 1980 paper reports lead content of around 7500 ppm Zinc at 1500 ppm. (Note that zinc is a ...

Firstly: Reuse of the oil for food use isn't a good one. Oil goes rancid. This is why you change the oil in the fryer. Alternataive uses: Here most restaurants have a grease and oil bin in back. It's collected to make soap. No reason you can't make your own soap. I use solid fat to make bird food blocks. The school I get it from changes the grease ...

It was already answered in answers for a more general question about driving (it's just on the top in the linked answer): it depends on speed. The slowing effect of an open window depends on speed qudratically, but it becomes really significant only at high speeds (more than 100 km/h according to what I know, though I can try to back it by some source if you ...

Peak oil - a red herring Peak oil is a red herring. And it always has been. The claimed problem of Peak Oil is that we have too few hydrocarbons, and in particular too little oil. And we know from climate science that we have too much hydrocarbons in reserve, including oil: the known reserves are sufficient to change climate so much that human ...

In your question you assume that it is then processed into biodiesel. This is not always the case, for example it can be converted in lubricating oil and glycerol to make soap. In the abstract of the paper Applications of Waste Cooking Oil Other Than Biodiesel: A Review many examples of applications apart from biodiesels are listed. It can be processed to ...

A: Reexamine your life style. How are you producing this fat? Can you produce less? Looking at our life, we probably produce about 4-5 tin cans of fat a year. When the can is full, it goes in the food garbage if it didn't get sidetracked to the dog dishes. (We have 3 garbage streams -- anything with food; recyclables -- paper, plastic, metal all meeting ...

If you have it available switching to natural gas will produce less CO2. If you have renewable energy surpluses, then TES (Thermal Energy Storage) makes lots of sense. You use MUCH larger water tanks, and heat it electrically when there is a surplus of power. Your air systems can be heated with hot-water fan coils -- cheap conversion. Look at roof ...
