1.Dependence on Foreign Oil = Bad. A number of reasons why this is true. OPEC members are ideologically contrary to the United States, and they have * a lot * of power over us. Obviously, they won't cut our oil supply or anything like Russia did w/ Germany, Poland and Ukraine in 2007, but in the event of war or embargo, we can be pretty much screwed. With our economy as volatile as it is, we really don't want to put our way of life into the hands of historic aggressors.
2.Environment + Pollution. I haven't exactly read Gore's Inconvenient Truth or anything, but the sentiment is pretty much widespread, and although lots of conservatives are citing scientists that say otherwise, the bottom line is that WE'RE SCREWING OURSELVES OVER. I think GHG (greenhouse gas) emissions are pretty much self-explanatory. This arg might be a double-edged sword, because some alternatives do pollute. Plug-in electric cars, for example, are ultimately run by coal because coal supplies a HUGE percentage of American electricity and not everyone can have solar panels because well it's kinda not sunny all the time. There are ways to process the dirty byproducts that are burnt from coal, but reprocessing is hella expensive and inefficient. BUT WAIT WE HAVE 30 YEARS TO PERFECT THIS SO FUCK ME.
3.Market Efficacy. Electric Cars have many market benefits. Imagine going to work, and your workplace's parking lot or garage has just installed overhanging solar panels. For a small fee (less than the price of gas) you are able to charge your vehicle while you work. The business benefits because it pays off the price of the solar panels + maintenance (and they eventually make money), the consumer benefits because he's filling up his car for cheap, and the economy benefits because now you can drive around more and shop. Better yet, imagine being able to do this for FREE at a mall or shopping place. “Hey come shop here and we'll fill up your car free!” Fuck yeah!
4.Alternatives fuels are cheap and reliable. Basically used in conjunction w/ the 'dependence on foreign oil = bad' argument, the aff can point out alternatives that can be made cheaply here in the US. Biofuels is one of these. Yeah, before you touch that FLAME button, I know about your crappy ass argument against corn + sugarcane biofuel (ethanol). You're basically gonna say that using these depends heavily on the season (in south america ethanol is GODDAMN EXPENSIVE when corn isn't in season...and imagine what happens when there's a corn BLIGHT!), and that it also drives up the price of food yada yada yada. HOWEVER. There is a potential for us to use ALGAE as a primary source of fuel. An average acre of algae can produce as much as 5,000 gallons of biodiesel each year, whereas an acre of corn produces 400 (http://www.worldwatch.org/node/5391). Algae is hardy and can be grown on fallow land bad for sugarcane or corn, isn't as subject to the weather or seasons, and can double its mass multiple times a day. In other words, it's FUCKI:N:G AWESOME. The only reason why it isn't being used today is because there currently isn't a big enough market for it. But under the conditions of this (shitty) res, this is totally feasible.
5.Alternatives can be regional. Flex fuel cars can run both algae biofuel and electricity. Solar power works when it's sunny, biofuels work when it's not. Furthermore, by splitting this up we destroy oil companies' influence and make sure that no single interest sways our politicians. They will adhere to markets in their area, like CA for solar and Kaintuck for its algae. I'll have to research more about the potential balance between these two pricewise.
