Citizens Who Care

The earth is warming, That is why we made this blog. It IS time to change! 20% of our world's population uses 80% of the world's resources. Oil prices are really low, $37 per barrel. People are using this money to get new cars. My family bought a new car, but I have mixed feeling about this. I know that it took a lot of oil to make the new car, and the old one will eventually end up in a landfill. However, since the car is larger I can carpool with my friends. According to the EPA, the average gas mileage of cars on the road is 24.1 MPG. This figure is one year old. This figure will probably decrease. This is because fewer mileage cars are "less" money than they used to be because gas prices are lower. That hurts the electric car market . It is less cost effective now because fuel for your Gasoline SUV is more cots effective than it used to be. Anyway... You can view the video  here Please note...

Hydroelectricity By: Samuel Desai Introduction Did you know that hydroelectricity is the oldest type of energy? Hydroelectricity was first used around 4000BCE when the Greeks invented the first water wheel. The water wheel took the current of the water to spin a wheel which could do many things. This early concept turned into hydroelectricity. Pros Hydroelectricity is extremely cheap. Existing dams can produce at about $0.0035 per kWh. SEI 2 Hydroelectricity is available at all times. Unlike wind and solar. SEI 2 Low replacement costs. All you need to fix is some concrete, piping, and a turbine SEI 1.5 Commonly used- Hydroelectricity already accounts for 48% of US renewable energy generation. SEI 1.5 Cons Droughts- because of climate change there is increased droughts. Take Nevada for instance. They are in the middle of a 15-year drought. The mighty colorado river is drying up. Which means less energy being produced. SEI -1.25 Environmental impact- When you dam

                Snow! By Kaden Chien Snow is an important resource. Snow helps us and the environment. In the winter, how much do you play in the snow? More importantly, is how the snow helps the environment. Snow cover helps to regulate the temperature. Once that snow melts, the water fills rivers and reservoirs. Snow also helps farmers. Farmers need the snow to blanket their fields so that when it melts in the Spring, the fields will already be irrigated. There are many different colors of snow such as black, gray, purple, blue, green, yellow, orange, red, and rainbow colored snow. Snow is endangered because of global warming. Despite the efforts to help global warming slow, it is still happening rapidly. It was even 64 degrees in December! Snow is a very important resource and we have to keep it.  RAINBOW SNOW!!!

Geothermal Energy By Tej Mehta Would you believe that a geyser can power your home? Well, it actually could. And it actually does power certain people's homes. The word geothermal comes from the Greek root Geo, which means earth. And therm, which means hot.  Geothermal is when heat is extracted from the earth, and that is basically what the word means. Geothermal  has its pros, but it has its cons also. One of the pros is that there is tons of heat, under the earth, and it can be extracted through volcanoes, hot spots, and geysers (SEI 2). It is also greener than other sources such as fossil fuels because it is renewable (SEI 1). It is renewable because when heat is extracted it can be re-injected. Scientists say that the amount of heat below the earths crust is equivalent to about 76 million barrels of oil. (SEI 2.5) The cons are that it is very hard to ship(SEI .75), and also, it can only be extracted in geothermal areas (SEI 1). Also, the earth's crust has to be d

Dear all wonderful blog readers, We are releasing blog version 6.0.1 Here are the changes: Changed it so that you can see the blog version in the description Got rid of horrible reaction button on posts Rearrangement of things on sidebars Got rid of things on sidebars We apologize for any inconveniences, Samuel, Alan, and Kevin Baer, a new tech support person (he also leads earth day)

The Rafflesia Flower The Rafflesia Flower, or rafflesia arnoldii, is the largest discovered flower on the planet, with a whopping bloom of 106.7 centimeters diameter and a weight of about 11 kilograms. It's commonly red, but there are many types of it. It's almost on the brink of extinction, and it's relatively hard to locate. Unlike most plants, it actually has genders, meaning that it's even harder to reproduce. The ratio of male flowers to females is disproportionate, making it harder to continue to multiply. It seems like everything is against this flower. It relies on parasitising only one sort of vine, and without it, it's dead. Deforestation also impacts it's chance for survival, since then the vines will be removed and it won't be able to live. It has to absorb nutrients, since it has no stem or roots, doesn't have chlorophyll, and depends on small threads that absorb nutrients. Almost no one has ever bothered to try and grow this plant. T

Wave Power: The future of energy  By: Samuel Desai Introduction Wave power (sometimes called tidal power)is a really new energy source. So there isn't a lot of info on it. However, we do know that the it has the potential to produce 2TW out of the 15 the world consumed in 2012. This means that it could provide a lot of energy. Pros Efficient-A wave farm the size of half a square mile can produce enough energy to power 20,000 average British homes. You could get as much as 100 MW per 1/2 square mile- SEI 3  Hidden- The generators are mainly underwater so you can only see a little bit of the generator- This will have no affect on tourism. SEI 2.5 Will be available forever. Solar energy will actually run out in 4 billion years, however, this won't happen to wave energy SEI 1 Cons Unknown environmental impact. There hasn't been any research on the effects of wave power on sea creatures. However, it needs to be done SEI 1.5 Costs. Wave power is new, so it i

By Nathan Shan Introduction: Wind energy is created when the wind turns blades on a wind turbine. The blades then turn a generator, which creates electricity. Large groups of wind turbines are called wind farms. Currently, wind energy accounts for about 4% of the U.S. power sector. Pros: Wind energy does not produce any greenhouse gases because it's not burning anything, so it doesn't damage the environment. SEI 2 Does not damage land or plants. Wind turbines can be installed without damaging crops, trees, or bushes, so it doesn't cause deforestation. SEI 2 Wind energy does not need mining, so there's no damage to the earth getting materials out. SEI 1.5 Wind power is 40 times more efficient than coal! In fact, it is the most efficient energy source. This allows the turbines  to convert a small amount of energy (the wind) into a lot of energy. SEI 1.5 Cons: The noise and shadows produced by wind turbines can cause health risks li

BIOMASS By Samuel Desai INTRODUCTION Do you think that energy can be made from poop? Well it can! Biomass is a type of renewable energy derived from plant or animal byproducts. Biomass is made up of many sub-topics. Biomass can come from algae, trees, poop (scientifically called feces, or dung),and even trash! PROS You can use things that would otherwise be wasted. For example, you can use the sawdust from mills which would otherwise be burnt in a landfills and pollute the air even more!SEI 2 You can use trash to decrease landfill size. We have a limited space in our landfills! In fact, people need to cut down trees to make room for a landfill, polluting the air in the process. SEI 2 CARBON NEUTRAL- You produce virtually no carbon in the process SEI 2 CONS Causes deforestation SEI -1 Counterclaim- You could use bamboo, which grows really fast, or something else. This makes this con only a SEI of -1  EXPENSIVE- It costs a lot to make a biomass plant SEI -2

Dear all, I mixed an  incredibox  song at  incredibox.com . Incredibox is a french company that makes sounds you can blend together to make wonderful music. You can check out our mix here . Thanks, The greencoldspring team! (note: if you note the title of our mix, sunrise, bothered to take a look at what time this post came out, and looked at the sunrise for December 4, you will be surprised!)

Weekly Endangered Species Report Yellow-eared Parrot By Matthew Gu The yellow-eared parrot, scientifically named the Ognorhynchus icterotis, is a somewhat big parrot(typically 42 inches long and about 285 grams) with green overalls that can be found in Tropical America. It eats bark, buds, and other plants. As usual, it's most common threats are deforestation, habitat loss, disease, and illegal pet trade. They're relatively social, often traveling in flocks of about 20 and sleeping in pairs. If a parrot is not in a pair, however, it'll most likely just sleep in different places around 2 to 5 palm trees. Thankfully, it's currently being preserved by informing local communities and protecting habitats. Although it was originally thought to be extinct, in 2014 it had about 1,103 individuals-not much, but a huge increase from before. The project might be considered a success, but overall we still need to be careful. Here's a picture of the yellow-eared parrot-

Tesla Model C & R: Too come soon? Not much is known about these cars. See the Tesla Forum for more. Here are some visions of the Tesla model C: These are the visions of the model R: Could the Tesla Model R really be Tesla's hyper car? Obviously the image above is not real. But none of these are probably real images.

By: Tej Mehta (sorry for the post  being late) INTRODUCTION Do you think that the sun will blink out during your lifetime? Probably not. That means solar energy won't be going away for a long time too. That proves that solar energy is reliable. Solar energy is when photons are allowed to knock free electrons from atoms, which generates a flow of electricity.   When it comes to storing solar energy, well, Tesla, has taken care of that. (see previous post Tesla power wall ) PROS There are many pros to solar energy, but there are cons. Some pros are that solar energy is extremely reliable. (SEI 2) It won't go out during our lifetime, and during future generations, unlike fossil fuels, or other energy sources. Solar energy is pretty much free once you get the panels. All you have to do is pay for the maintenance, and storing the energy. (SEI 2) The sun produces enough energy to power about 2880 trillion light bulbs! Also, the sun constantly gives the earth about 35,000 ti
