In the summer of 2001, The National Environmental Education Foundation conducted a survey of 1,503 American adults about energy. Although 75% of those surveyed said they knew “A Fair Amount” or “A Lot” about energy, only 12% could correctly answer 7 or more questions on a 10 question energy quiz cheap adderall adderall generic here . The quiz is on pages 4 and 5 of the report (pages 15 and 16 of the PDF) there buy valium online no prescription today there . So what’s your “energy IQ”?
The discussions about a carbon tax, or a cap-and-trade system, tend to revolve around “putting a price on carbon,” which is to say, charging polluters money for dumping carbon into the atmosphere. But how should that money be used? Here’s a graph from Vattenfall, the Swedish power company, showing which solutions purchase accutane click here buy accutane online canada become cost-effective at a price of €40 per ton of carbon dioxide prescription adderall adderall generic buy adderall australia .

The green section has the improvements that will be cost-effective at the €40 price, and the blue section has the more expensive solutions.

This list of action items for individual energy savings is the most focused and quantitative I’ve seen. It comes from an October 2008 article in Environment Magazine by Gerald Gardner, professor emeritus of psychology at the University of Michigan-Dearborn, and Paul Stern from the National Research Council buy adderall us adderall generic adderall cheap .
The actions in the list are grouped by whether they’re for transportation or inside the home, immediate or longer-term, and no-cost/low-cost or higher-cost valium online without prescription buy valium online no prescription today valium uk . Each item also includes an estimated percentage savings of total energy use purchase accutane click here buy accutane uk . Here’s an example of an immediate, no-cost action for everyone:
Heat: Turn down thermostat from 72°F to 68°F during the day and to 65°F at night
A/C: Turn up thermostat from 73°F to 78°F

In earlier years of Lawrence Livermore National Laboratory’s spaghetti diagrams, such as the above example from 1976, the ends of the swaths were more like the simpler energy flow diagrams. On the above diagram it’s easier to see that the height of the lines on one side would end up around the height of the lines on the other side than it is on some of the newer versions with oversized boxes that serve as labels. But the boxes are a useful tool, and can let us think about embedding another diagram form — box diagrams — into the spaghetti diagram.
Box diagrams are used for teaching electricity, and were developed by Peter Cheng and David Shipstone in the UK. The picture below is from part 1 (Word doc) of their introductory paper (here’s the Word doc part 2). Since power is the voltage across a bulb multiplied by the current [...]
This “spaghetti diagram buy adderall no prescription adderall generic adderall without a prescription ” (aka Sankey diagram, or Energy Flow Chart officially) is the 2008 version. Lawrence Livermore National Lab (LLNL) has been making these things since the 1970s. It’s more detailed than a simpler national energy flow diagram because it includes “rejected energy.” It’s also more complex — it actually includes within itself the electricity flow diagram. It’s a pretty cool visualization.
The main thing I dislike is that it doesn’t split up transportation or electricity generation “rejected energy” by sector. Since these are really the two biggest sources of “rejected energy,” you can’t see which group is the biggest “rejector generic valium information buy valium online no prescription today valium online usa .”
Below, in an undated but funkier design, they’ve not only split up transportation into light duty vehicles, freight/other, and aircraft, they’ve also added domestic and net [...]
Here’s a picture from What You Need to Know about Energy by the National Academy of Sciences. It shows 100 energy units of coal being used by an incandescent bulb ativan online usa buy ativan mexico where to buy ativan without prescription to produce light that has only 2 energy units:

Incandescent bulbs get hot because only 2/36 (about 5%) of the energy coming into the house to power the bulb comes out as light — the rest of the energy produces heat buy accutane online no prescription today click here there . If you trace the energy back [...]
Here’s a document from 1982, A Conceptual Framework for Energy Education, K-12, commissioned by the Department of Energy. On page 7 is a description of an “energy-literate citizen”:
Understands that we can’t make energy.
Finds more efficient ways to use energy at home, at school, and on the job, for example through the use of waste heat buying adderall adderall generic buy adderall online usa .
Has some historical perspective on energy use ativan pharmacy buy ativan mexico buy ativan fedex and extraction; for example, has an informed notion of where we stand on the fossil fuel depletion curve.
Compares life-cycle costs in deciding on major purchases valium cheap buy valium online no prescription today buy valium online usa .
