It is a start of a new year, and there is one energy I want to talk about that dramatically increased in 2014. It is called geothermal energy and it increased 5% last year. Geothermal energy is just heat coming from the Earth. Starting in the 1970s different countries started using it for energy. Most geothermal systems go 10,000 meters into the ground. The temperature underground for most of it is 65-75 degrees. There are many pros of geothermal like how it is green because it releases barely any emissions, zero carbon, does not take much land, and can be used mostly everywhere. But of course there are negatives to every energy. Geothermal energy usually are faraway from people, long transmission, water usage, and high construction costs. I do like how geothermal is one of the cleaner type of energies, but I think it definitely needs improvement. It seems really dangerous digging into the ground because I feel like it could lead to water pollution. I also do not like how it usually has to be away from people because you lose so much electricity and money that way. Most people are familiar with Yellowstone National Park's geysers. but those are not used for electricity.
The U.S. is the biggest produce of geothermal energy and we generate 15 billion kilowatt hours of geothermal power per year which is 0.41% of U.S. energy. There was an article I read called "The Dream Becomes Real: Touring the Newberry Enhanced Geothermal Site" by Renewable Energy World. I really liked this article because it talked about how they are determined to get the plant up and running, but with everything there are some complications. In Bend, Oregon they are building the Newberry geothermal project. It has 5 GW of potential. The U.S. has a potential of 345,100 more MW of power, which could help the environment by moving away from coal. Most geothermal plants use existing reservoirs, but this project is creating its own by drilling into dry rock and injecting liquid to make the reservoir. This project's opening has been postponed two years now because there was a leak which released 10 million gallons of water! This could have been very dangerous because it could have caused an earthquake. It should be ready in spring of this year and reach almost 10,000 feet.
I think this project is amazing. I love how they figured out new ways to get the energy. It is not really damaging the landscape and it provides a lot of clean energy. We should really try to do more projects like this in the future, so that we could move away from. We still need to improve our technology because it has been delayed so much time, and we waste so much water getting the heat. I hope that when they do start running the project, that nothing will go wrong like polluting the water supply. But this project is great news to the environmental community!

The Growth of Renewable Energy
I was going through Washington Post articles and one caught my eye. It is called "Renewable Energy is Growing Very, Very Fast. It's Just Still Not Fast Enough." It says how renewable energy production increased by a big amount from last year. The worldwide investment in renewables in 2014 was $270.2 billion which was a 17% increase from 2013. There were many solar projects in Japan and China and offshore wind farms in Europe. Surprisingly half of the investment was in developing countries.Solar and wind were the two many sources for the new energy; taking 92% of the investment. About $150 million investment was in solar and $100 million in wind. Since countries are investing more in renewables, the price of solar and other technologies has gone down. The new technologies are more energy-efficient which means we are investing more in renewable energy, but are now making a lot more money on it. China was the biggest investor with $83 billion than the U.S. with $38 billion and then Japan with $35.7 billion. Renewable energy is now 9.1% of the world's energy consumption which is a 0.6% increase.
This article made me happy that renewable energy is growing fast, but it is still kind of slow if that makes sense. Just like the article title says it is just not fast enough. Billions of dollars are going into renewables, but renewable energy is only 9.1% of energy production. That number is so low! It is not even in double digits yet. I know renewable energy technology is expensive, but it getting cheaper now so hopefully more countries invest. Maybe if people stop buying their stupid SUVs and we can get cheaper solar panels that would help by a huge amount. In college I want to major in sustainable energy management so this information gives me confidence that I will get a job after graduation. The U.S. is the second biggest investor in renewables, but of course we are behind China like everything else in the world. Hopefully every country in the world invests in renewable energy so that the world can be a sustainable, healthy place to live.

All About the Keystone XL Pipeline
If you pay attention to the news, you have probably heard about the Keystone XL Pipeline. It was a big issue in 2014 and it has now continued into 2015. If you have not heard about it, it is a 2,000 mile pipeline that flows oil produced by tar sands in Canada and it runs all the way to Texas. Many people are for it because of the 120,000 jobs and increases the about of oil we produce domestically so oil will be cheaper. If you're an advent reader of my blog, you know I am interested in anything to help the environment, and so I wanted to see why environmentalists were fighting the Keystone XL Pipeline. An article by the Labor Network for Sustainability really had some great points. It said that "To produce one barrel of heavy crude oil from tar sands requires strip mining the forest, extracting four tons of earth, contaminating two to four barrels of fresh water, burning large amounts of natural gas, and creating vast holding ponds of toxic sludge." Now I see why Republicans are mainly for the Keystone is because they do not care about the environment. This project is taking down trees and destroying habitats for animals. And what happens if there is an oil spill? There will be oil over 2000 miles of land! I know people need jobs, but is it worth the risk? I do not think so. People are putting jobs over our beautiful environment. Another point the article talks about are the rising greenhouse gas emissions and this project will increase them even more due to the deforestation and burning of coal.
Last week there were big news about the Keystone XL pipeline. In the article "Obama Facing Rising Pressure on Keystone Oil Pipeline" from the New York Times discussed how the House passed a bill approve the Keystone in Nebraska. The final vote was 266 to 153. The representatives who supported it said that the pipeline will bring 830,000 barrels of oil per day to the Gulf Coast, creates jobs and adds 3.4 billion to the economy, is domestic, and it does not increase greenhouse gases as much as environmentalists said it does. Another claim they have is that it will not destroy much of the environment. The Nebraska governor approved it after the pipeline company, TransCanada, changed its route to avoid the Sandhills region. Even with all these great pros I still doubt their sources and I hope the President vetoes it. We need to protect the environment and the Keystone Pipeline will destroy it. We should be moving away from oil, not try to get more of it. It would be best to invest in renewable energy, and I hope President Obama thinks the same way.Sunday, January 4, 2015
Hydrogen Fuel Cell Vehicles
In my other articles I have discussed electric cars and gasoline-powered cars, but have you ever heard of a hydrogen fuel cell car? Using hydrogen as a power source is not really a new technology-NASA has been using it for 50 years-but now Toyota is now using that fuel for cars. Hydrogen fuel cars work like this:
I think it is so fascinating how we could just use water to power a car. It has no emissions so it is amazing for the environment. I think it is kind of weird for water to leak on the streets. I know this will be way ahead in the future, but what if everyone gets a hydrogen car, then there will be a lack of water, and cause corrosion of the streets and our sewers will get full. I read a really cool article from the magazine Bloomburg BusinessWeek called "The World's Biggest Car Company Wants to Get Rid of Gasoline." That title really got my attention, so I was excited to read it. It discussed Toyota's huge move to create the first mass-produced hydrogen car called the Toyota Mirai.
It has a driving range of 300 miles and emits only heat and water. It is on the market in Japan, but does not go on the market in the U.S. until the end of this year with a price tag of $62,000. It does not go pretty fast. The problem with hydrogen fuel cell cars-sometimes the same problem as electrics-are the lack of fueling/charge stations. There only 8,849 electric stations and 21,916 charging outlets in the U.S. And since hydrogen fuel is so new we only have 20 stations in the whole U.S., mostly in California. There are a lot of other car companies like Tesla who really question the reliability and benefits to the environment hydrogen fuel cars have. I feel like scientists should gather more evidence to settle this dispute. Another problem the article discusses is that even though they have gotten the price of hydrogen lower, making it cheaper than gasoline and electricity, hydrogen can be a very dangerous fuel. It is highly explosive which is very scary to me. Imagine if there is a gas leak on the road, there is a chance the car could explode! Toyota said they handled most of those issues, but I am still not 100% about trusting them. For me this car is so new, and nothing has come out like it, and so I do not know how it is actually going to be. Hydrogen is not easily made into fuel, and we do release emissions while changing it into a fuel. We need to reduce our emissions, global warming is upon us, and I really admire Toyota for being different and trying to help the environment, but we will just have to wait and see how successful these cars are in the long-run.

Bioenergy
Bioenergy is energy from living materials such as plants, wood, and waste. It is the biodegradable fractions of products, wastes, and residues. Therefore, it is a renewable energy source. Plants are the most used source for bioenergy because they are the easiest to grow. Carbon dioxide gets removed during photosynthesis and the net emission of CO2 could be equal if we keep replenishing plants for bioenergy. Biofuels convert biomass into fuel for transportation, biopower burns biomass to generate electricity, and bioproducts are products made from converting biomass into chemicals. America is really trying to improve bioenergy and make it used more frequently all over the United States. It is the most used renewable energy technology in the U.S. by a huge amount.
In an article on energy.gov called "Energy Department Announces $7 Million to Develop Advanced Logistics for Bioenergy Feedstocks" it talked about how that money is going towards two projects to help reduce the costs of transporting biomass to biorefineries. Sometimes the places where they grow the biomass are so far away from the refineries and so they are transported on trucks(with bad gas mileage) on long distances to the refineries. With this project, we could reduce the costs of biomass so that if we make biofuels it would be a lot cheaper than gasoline. They are developing better technology for more efficient and lower-costing harvesting, collection, and transportation of biomass. I am really happy about this news because we are using so much biomass, but we should always look for ways to how to improve the process. They are also using two colleges for help on the project which I think is really cool because it gives them more experience for their future careers.
And the U.S. Department of Energy is not stopping with that project! They are donating $14 million for another biomass project. In another article by energy.gov it said they are using "landscape design approaches that maintain or enhance the environmental and socio-economic sustainability of cellulosic bioenergy through the improvement of feedstock production, logistics systems, and technology development." Their focus is making renewable energy more commercialized and reducing carbon emissions. An example would be using corn for fuel and water quality by improving agricultural residue. Energy is a business and I think is good news that they are using biomass in not only its energy form, but also making the landscape better as well. They are making our technology more efficient which will lower costs so that renewable energy can be more abundant and cheaper. Obviously the U.S. is moving towards biomass and it is no surprised why.

Nuclear Energy
Nuclear energy is America's third-largest source of electricity after coal and natural gas. Nuclear plants produce electricity by boiling water into steam which spins turbines. To create nuclear power we use uranium fuel which contains solid ceramic pellets, and the process is called fission. Nuclear energy is a renewable source and it produces no greenhouse gas emissions. The problem with nuclear energy is the radioactive waste it produces which takes years to finally decompose and the accidents that may occur.
In the article, "Before We Close More Nuclear Power Plants, We Need A National Conversation" (Fox News) it explained the problems with nuclear power in the U.S. More nuclear power plants are closing due to "sluggish demand for electricity, the onset of cheap natural gas, electricity markets that do not sufficiently value low- or zero-carbon electricity sources and an aging, constrained transmission system." There are also public concerns on disasters. I feel like most of the U.S. does not care about clean energy and the world deteriorating. Everybody cares about natural gas too much and that is not renewable. Like I said in my other posts non-renewable sources should pay higher taxes, and more money should be going to renewable sources to create better carbon-free energy technology. If we shut down more nuclear power plants, we would be taking away thousands of jobs and the CO2 will increase dramatically.
In another article I read from US News was called "Despite New Plants, Nuclear Future Still Decades Away." We have just opened two brand-new nuclear energy plants! This is great news. We have not created a new power plant in 30 years and now we have two new ones! But it did cost 15 Billion which is a lot of money, but was totally worth every penny because it makes peoples energy bills go way down and it is clean electricity. There is a future in nuclear energy and the U.S. Department of Energy sees this. They are allotting 450 million to two new projects which will take about ten years to complete. The Environmental Protection Agency is now trying to make laws for stricter emissions limits for coal-fired power plants. It will make coal producers to install new technology which will make the price of coal go up by about 75%.
Even though there are many doubts about nuclear energy it will one day surpass coal as the biggest producer of electricity and the world will be a much cleaner place to live.

Wind Energy
Wind energy provides only 2% of the total electricity supply. The United States is trying to improve that because it is clean energy, but so many people are really against it including environmentalists. An article by Fox News called "It May be Lights Out for the Wind Energy Come the Midterms." In the article it talked about how wind energy makes peoples' taxes go up. It says a study shows that the states with the most wind farms have the highest electricity bills. The Production Tax Credit is a federal programs that gives out billions of dollars annually to renewable energy companies. To pay for the wind farm taxpayers have to pay taxes for it for ten or more years. The League of Conservation Voters has deep ties with the American Wind Energy Association and some of them are on their committee and together they are a powerhouse.
I did not know that Republicans cared so much about the environment, I thought mainly Democrats only did. But the article does make a good point that the Republicans are getting so much money from the wind energy companies, so they might not even care about the environment, only the money. It is more like a business to them. I really want the U.S. to push towards renewable energy, and wind is a great option in the Midwest, but we need to find better ways to make it cheaper because it is ridicules how we have to pay millions for it and taxpayers have to suffer from it when clean energy should be helping people.
Another article I read from Fox News was called "Bird Conservation Group Challenges Feds Over Wind Farm Eagle Deaths." The American Bird Conservancy has a lawsuit against Obama for giving wind energy companies land permits to kill bald and golden eagles and they are not getting prosecuted by the government. It is for Obama's plan for green energy, and he is giving them permits for thirty years. Wind turbines blades can go up to 170 mph making it like a deadly tornado. Wind Farms in 12 states together have killed about 250 eagles. The U.S government has only sued one company in Wyoming for killing eagles and other birds from their wind farms.
Wind energy reduces greenhouse gas emissions and in the U.S. provides clean energy to 15 million homes. In January of 2015 a law in Colorado will take effect protecting the birds and other wildlife from wind energy. It is the first law in the U.S. of that kind.
I did not realize wind energy is killing this many species. Bald eagles have just gotten off the endangered species list and I definitely do not want them on it again. I was totally for wind energy because it is clean and green, but I am totally rethinking it now. I knew there is always drawbacks to everything, but I did not know they were this bad. Maybe we could use other designs like bladeless wind turbines like the Dutch's Ewicon, so that no other animals get killed.
