What conservatives don't seem to get is the fact that renewables will always be here for humanity. No pollution, no health effects from that pollution, little environmental damage comparably and cheaper.
20 years from now solar will be seen as the conservative energy as it will be common sense. Simply economic.
20 years from now -- folks with common sense will be seeking you idiots out who claimed "no pollution" from renewables and forcing them to dump the waste stream from
THIS into THEIR backyards..
THAT'S the massive battery barns that have to be built to cope with more than a few percent of flaky, intermittent renewables on the grid.. HUNDREDS of TONS of batteries with limited lifetimes and a list of toxic contents.. That little number there is about sufficient to handle a couple dozen wind turbines. Or the brown-out from a mid-size cloud passing overhead for a medium size commercial solar farm..
Q: How often do you have to replace the batteries?
A: Nickel Metal Hydride batteries (NiMH) are proving to be very long lived. Several cars with over 130,000 miles have been reported with virtually no range degradation. Estimates of 150,000 – 200,000 miles are predicted. Lithium Ion (LiIon) is thought by most experts to be the chemistry that will supplant NiMH. The testing of battery life is continuing, but it’s too early to tell how long LiIon will last.
Q: What if electric cars get their energy from dirty sources like coal – how clean are they then?
A: The Argonne National Labs have looked into this issue and report that the mix of power in the electrical grid, not all of which is coal, results in a 32% decrease in greenhouse gases with EVs. The other pollutants similarly meet the stringest standards for the cleanest gas cars today, even charging completely from an ordinary coal plant. Many states such as California are much cleaner, with a grid mix at 29% coal. EVs also allow you to use 100% clean renewable electricity from sources such as the sun or wind. In addition, EVs get cleaner as the electrical grid gets cleaner. Gas cars only get dirtier as they age. We support replacing all “fossil-fuel” electricity generation with clean and renewable generating methods.
Q: ArenÂ’t all those batteries full of toxic chemicals and precious metals that will just end up in a landfill?
A: Not at all. Every car in the world has a lead-acid battery, the most toxic metal used for batteries. Even with its low value as scrap, the recycling rate for lead-acid batteries is about 98% in the U.S. EVs will use newer chemistries such as NiMH and LiIon. Both of these metals are inherently more valuable than lead, and since the batteries are quite large, the value of the spent battery packs will be such that the recycling rate will approach 100%. It is illegal to dispose of these batteries in a landfill and their value will ensure that is not their fate. Nickel, while mildly toxic, will be reclaimed during the recycling process. Lithium is even less toxic and more valuable than nickel.
Q: How viable are hydrogen cars? Many seem to think they are the "cars of the future.”
A: There are two types of hydrogen cars. Fuel cell vehicles (FCVs) are EVs, but instead of getting their electricity from batteries charged from the grid, they get their power from fuels cells using hydrogen as the energy carrier. FCVs use four times as much electricity on a per mile basis as a battery EV if the hydrogen is obtained through the process called electrolysis. So you would need four times the number of solar panels to go the same distance as you would in a battery EV. Hydrogen obtained through reformation of hydrocarbon fuels releases massive quantities of CO2 into the atmosphere, and even that dirty process uses more energy than merely charging a battery. FCVs have many seriously difficult and expensive engineering challenges to solve before they will ever be widely available, and even then, the energy required per mile will probably still be substantially higher than with battery EVs.
Internal combustion engines (ICE) can be made to burn hydrogen instead of gasoline. Even these fairly simple conversions are expensive, and the energy required is again, much higher per mile than with EVs. In addition, ICE burning hydrogen (H2) cars still have some emissions albeit low but they cannot be considered ZEVs, not even taking into consideration how one gets the hydrogen.
The bottom line is that there is no advantage to using FCVs or H2 ICE technologies over battery EVs.
