James asks...WHICH OF THE FOLLOWING PROCESSES IS NOT REGARDED AS CONTRIBUTING TO THE CREATION OF GREENHOUSE GASES? deforestationcreating electricity from coalcreating electricity from WINDuse of fertilizersWINDMILL FARMS ANSWERS: Creating electricity from wind http://en.wikipedia.org/wiki/Greenhouse gas http://en.wikipedia.org/wiki/Wind power Steven asks...WHAT TECHNOLOGY COULD WE USE IN THE FUTURE TO REDUCE GREENHOUSE GASES? For Homework, I am required to research about a piece of technology we could use in the future to reduce GREENHOUSEGASES but I have had a look to see if there are any but I could not find anythingWINDMILL FARMS ANSWERS: Gee Sage are those classifieds as pearls or pellets of wisdom pellets I guess We can use the technology we already have. Wind, Solar and Geothermal power and alternative fuels. The technology is already available to us. What we need to do is innovate, create and perfect these. William asks...ARE ELECTRIC VEHICLES REALLY ENVIRONMENT FRIENDLY? They seem to be if we go by no emissions as compared to fuel fed vehicles. But don't they emit bad vapors in the air, too when the batteries are being recharged? And in the long run, what happens when billions of batteries die out and needed to be replaced? Where do you dump them or what's left of them? They would surely pollute big time. So is it really a good alternative against fuel fed vehicles?WINDMILL FARMS ANSWERS: Yes, they are. The batteries are fully recycleable, for starters. The following quote is about hybrid batteries, but the same applies to electric vehicle batteries: "Toyota has a comprehensive battery recycling program in place and has been recycling nickel-metal hydride batteries since the RAV4 Electric Vehicle was introduced in 1998. Every part of the battery, from the precious metals to the plastic, plates, steel case and the wiring, is recycled. To ensure that batteries come back to Toyota, each battery has a phone number on it to call for recycling information and dealers are paid a 200 "bounty" for each battery." http://www.toyota.com/about/environment/technology/2004/hybrid.html Electric cars are refueled (batteries recharged) from the power grid, which does create greenhouse gas emissions. However, because the efficiency of these power plants and electric engines is much greater than the efficiency of burning gas, you still get a large overall reduction in greenhouse gas emissions. The greener the power grid (more renewables like solar, wind, water power), the lower the emissions created to refuel an electric vehicle. ICE = gasoline car (internal combustion engine)HEV = hybrid gas-electric car (uses gasoline to recharge batteries)EV = electric vehicle (plugs in to recharge batteries) "EVs reduce CO2 by 11%-100% compared with ICEs and by 24%-54% compared with HEVs, and significantly reduce all other greenhouse gas emissions, using the U.S. Grid mix. If all U.S. Cars were EVs, we'd reduce global warming emissions. Using electricity strictly from coal, EVs still would reduce CO2 by 0%-59% compared with ICEs (one analysis found 0% change; six others found reductions of 17%-59%) and might produce 30%-49% more CO2 than HEVs (based on only two analyses). On the other hand, if electricity comes from solar or wind power, EVs eliminate all emissions. Using natural gas to make electricity, emissions fall in between those from coal and renewable power." http://www.pluginamerica.com/images/EmissionsSummary.pdf Mary asks...HOW'S FIREPLACES ENVIRONMENT-FRIENDLY? I mean the smoke that gets out of the fireplace, is that Environment-friendly? like how can that be when all the smoke goes up?WINDMILL FARMS ANSWERS: Honestly, they aren't!The wood that burns in fireplaces comes from trees that have been cut down clearing earth's forests of their vital plantation. Without trees our planet would be as smelter scorching hot as Venus, the inferno sulfur cloud infused desert rock planet. To much wood burning also causes carbon monoxide to infuse our earth's skies making our ozone layer worse. Our ozone layer is supposed to protect us and all other life forms from sun's solar ultraviolet rays preventing our planet from becoming another Venus inferno sulfur cloud infused desert rock planet and at the same time maintain a normal mid-temperate climate preventing our planet from becoming icy cold like the polar ice planet Pluto. Too much toxic fumes, such as smog caused by burning fossilized fumes infusing our atmosphere, carbon monoxide traps more heat at the surface of our planet making our planet's greenhouse gas effect worse. Fireplaces burning wood from trees cut down from forests cleared away through fire uses up earth's natural resources just as much as running the heater through gas and/or electricity. Gas comes from fossilized remains at the bottom of earth's abyssal ocean floors, which could do damage to earth starting with the oceans, seas, reaching the lakes, straits, rivers, ponds, savannas, mangroves, streams and creeks, aquatic plants, aquatic animals, aquatic creatures before reaching land and evaporating through the atmosphere within our skies. Electricity comes from wind power paneled through water into funnels and wind power paneled through wind mills. Too much electricity use can use too much pressure in water funnels and wind mills creating greenhouse gas effect. When volcanoes erupt the only good thing that comes from that natural disaster is new land forming, new mountain ranges on land, above and below ocean floors.Actually many underwater mountain ranges could make sailing dangerous and difficult just as brutal as the Titanic when the captain hadn't realized about 70% of the actual ice berg was submerged underneath the arctic ocean. Helen asks...HOW CAN HYDROGEN HELP REDUCE THE GREENHOUSE EFFECT? chemistry homework help please !WINDMILL FARMS ANSWERS: When we burn hydrocarbons (such as gasoline or diesel) they produce CO2 vapor, which has been proven to be a greenhouse gas. If we burned Hydrogen for power, it would only produce water as a byproduct. However, it is important to note that the large majority of hydrogen produced in the world is currently made from hydrocarbons. So if we decided to run our cars on hydrogen, our cars would only produce water byproduct, but the refineries where the hydrogen was made would still produce the CO2 in making the hydrogen. If we want to reduce the greenhouse effect, we would need to start producing hydrogen by splitting water molecules using electricity. However, currently we generate the majority of our electricity in the US from burning coal (which creates a large amount of CO2). So- to answer your question, if we used renewable (solar/wind/water) sources to generate electricity to create hydrogen from water, we can reduce our CO2 production and reduce the greenhouse effect generated from it.
