How to Make a Cool Home

Air conditioners are bad for the environment so it’s obviously good if you can avoid using one. It’s easier than you think! At Freshome they have complied a handy list that has many tricks to keep your house cool without using AC. Over at PlanetFriendly there is a list of alternatives to air conditioners.

From Freshome:

The most common sources of internal heat gain are; appliances, electronic devices, and lighting. Be aware from where the heat is comming. Now if you have air conditioning, use it wisely. Don’t put lamps, televisions or other heat-generating appliances next to your air-conditioning thermostat, because the heat from these appliances will cause the air conditioner to run longer. The heat they produce will make it think your house is warmer than it really is, and your system will run harder than it needs to.

US Congress Aims for Carbon Neutrality

The old saying “better late than never” comes to mind here as the United State’s Congress has decided to go carbon neutral by 2020. It is impressive that congress has decided to do this in a nation that has a leader that denies climate change. The fact that congress is trying to become green will hopefully send a message that being environmentally friendly is something that any institution can do.

What stands out for me is that they go beyond carbon neutrality and encourage a bike-to-work program. Good for your health and the environment!

Reducing energy usage is not all that is covered in the report, as it also calls for the use of non-toxic cleaning products, increasing water conservation, and significantly improving recycling, improving access to mass transit and car sharing for employees, changing the current fleet to hybrid vehicles, purchase locally and organically sourced food, changing to 100% recycled paper, and even implementing a bike-to-work program.

Harder, Better, Faster, Stronger

No this is not a post about that Daft Punk song, this is about car batteries. Wired is reporting that the next generation of car batteries that are currently in development are going to be better, work harder, allow for faster cars, and hold a stronger cars. Essentially car battery technology is improving thus opening up more possibilities for electric cars.

Firefly has replaced the lead plates found inside conventional batteries with a lead-impregnated foam made from carbon graphite –- one of the few materials that can withstand the highly corrosive sulfuric acid inside batteries. The foam increases the surface area of lead inside the battery, delivering more power and slashing the recharge time, says Firefly CEO Ed Williams.

Equally important, Firefly’s approach eliminates the crystals that can build up inside lead-acid batteries. Over time, those crystals reduce the amount of electricity a battery can hold, one of the major reasons electric and hybrid automakers have favored lithium-ion or nickel batteries, even though lead acid is less expensive.

Tidal Power for San Francisco

Golden gate
Readers of this site may remember that San Francisco spent some money investigating the feasibility of tidal power for the city last September. Well, things are definitely going good with that study has it’s entered a new phase. The San Francisco, Pacific Gas & Electric Co. and Golden Gate Energy Co. have agreed to further the study and invest $1.8 million into it. If this next phase goes well it may open up more opportunities for tidal power generation as the San Francisco project will have to take into consideration many factors that may deter other cities from trying such an initiative.

The $1.8 million study would seek to determine how much electricity could be generated, what kind of technology would work best and whether the project makes sense economically. It would also examine the project’s possible impacts on marine life and the environment.
