So if we have all these different sources of renewable energy how do we work them into our electricity grid system effectively? The demand for energy is skyrocketing as everything in our world is beginning to rely on electricity from cell phones to cars. "[The demand] is expected to grow at an annual rate of 2.2 percent – and climb from 20,300 terawatt-hours today to 33,000 terawatt-hours by 2030." (Siemens) Well, while companies embracing renewable energy could try to promote it individually it probably won't work for widespread use of renewable energy... What many pig power companies like Siemens and Cisco are trying to achieve is an updated "grid", which is what brings energy from the power plants to our homes. This grid using internet and computer technology to communicate with various sources of power drawing from different sources such as solar, hydro, and wind all at the same time and using whatever is producing the cheapest source of energy etc. This greatly reduces the dependence on fossil fuels for our energy production. This video explains the concept of a "SmartGrid" more scientifically and in depth. :D



Overall this brings the outdated grid system we have into the new age of technological advancement and is a great transition to encourage people to be more "green" hence saving more green! That's what people like to hear! The system integrates the different sources of energy together into one larger system and this, if done properly, could be just the change the world of power production needs to see!

Get your Geotherm On!

Geothermal Power is harnessing the natural power of the interior of the earth for our advantage. The heat from the inner layers of the earth such as the core and mantel heat underground sources of water, which can be used to turn generators above ground to produce electricity. It’s also extremely efficient to heat and cool buildings. In fact, geothermal heat pumps are the most energy efficient, environmentally clean, and cost effective systems for temperature control according to the EPA.

It is estimated that the northwest has the potential to generate more than 2,600 average megawatts of electricity from geothermal power this is enough energy to meet the annual needs of almost 2 million average homes. Naturally occurring large areas of hydrothermal resources are called geothermal reservoirs.

geothermal energy sometimes finds its way to the surface of the earth in various ways such as:
• Volcanoes and fumaroles (holes where volcanic gases are released)
• Hot springs
• Geysers (like ‘Ol Faithful)
Hot water near the Earth's surface can be piped directly into buildings and industries for heat. This is called a “district heating system”. A district heating system provides heat for 95% of the buildings in Reykjavik, Iceland!In Iceland they use a lot of geothermal power!



So, How does geothermal WORK? : WELL there are different types of geothermal plants. The first one we’ll talk about is

• FLASH TECHNOLOGY: They take high-pressure hot water (water from 300 to 700 degrees Fahrenheit) from deep inside the Earth and convert it to steam to drive the generator turbines above ground. When the steam cools, it condenses to water and is injected back into the ground to be used over and over again. Most geothermal power plants are flash steam plants. One downside of this is that there is a risk of polluting the water.
• DRY STEAM PLANTS: They use steam piped directly from a geothermal reservoir to turn the generator turbines.
• BINARY CYCLE PLANTS: They transfer the heat from geothermal hot water to another liquid. This water is a lower temperature than in Flash Technology. The heat causes the second liquid to turn to steam, which is used to drive a generator turbine.
Geothermal wells are dug one to two miles underground typically.

The top picture is a factory type set up the bottom is a residential set up.

Geothermal Plants are very high in their initial expense, but geothermal plants have reasonable operation and maintenance costs and no fuel costs. Also unlike solar and wind geothermal plants can generate electricity 24/7.

Overall geothermal is still being developed into a realistic option but if there is enough capital to invest in plants in the North West it could definitely compete with fossil fuels and other alternatives in the way of producing a large chunk of America’s energy renewably.

Wholesome Hydro!

Now that we’ve explored the pros and cons of using biomass as an alternative for fuel use let’s talk about good ol’ water. Hydroelectricity is an industry that accounts for about 67% of the renewable energy production in the United States, but only 6% of the total energy production. :[ Hydropower relies on changes in elevation and lots of rain in order to produce significant quantities of electricity.

How does Hydro work? : Well, the movement of water as it flows downstream creates kinetic energy that can be converted into electricity. Lets take a look at the process…

“Currently, facilities in the U.S. can generate enough hydropower to supply electricity to 28 million households, which is equivalent to about 500 million barrels of oil.” Imagine if we were able to increase the number of facilities therefore reducing our dependency on oil greatly. (http://www.epa.gov/RDEE/energy-and-you/affect/hydro.html)

Hydropower has no air quality impacts reducing the number of greenhouse gases emitted but it does take a toll on the fish populations. Though some plants have employed systems that track the fish and they make certain that no harm is done.

There are different types of hydroelectric plants. There are those that function off of natural forces from the current apply the needed pressure (which are least disruptive) known as “run-of-the-river systems” and there are those that create dams to make an elevation difference known as “storage systems”. Wave power and tidal power, which are more predictable than wind and solar are also forms of hydroelectric activity.

Overall harnessing the power of the the water our world has so much of is a great way to buff up our renewable energy production!

Biofuel Rules!

In the flurry of talk about renewable resources common themes seem to be wind and solar. While both of these are viable options, today we’re going to delve into something that has been on the rise as of late. Biomass Fuels. Surely you’ve heard of bio-diesel cars but lets look a little further. Biomass fuels can also heat homes and create electricity.



WHAT IS BIOMASS?
Biomass fuel is anything that can decompose or burn. Some examples are fast growing grasses, trees, and even urban and agricultural waste such as grease from restaurants or sugar cane husks.



HOW DOES IT HELP?
There are many positive effects to using bio-fuels in our homes and vehicles. Here are a few environmental/economic gains:
1) By growing our fuels here in our own country, we reduce the need to import oil and reduce our exposure to disruptions in that supply.
2) Farmers and rural areas gain a valuable new outlet for their products, a whole new market in a way. & also creating a large amount of jobs.
3) Construction and demolition wood, yard trimmings and non-recyclable organic material are all consumer waste that can be used as biomass to create energy. Grease from restaurants can also be turned into fuel.
4) It reduces water pollution because there are fewer pesticides used to grow energy crops. It also reduces erosion by catching runoff if planted near waterways cleaning up streams.



WHAT ARE SOME BIO-FUELS
The 2 most common are Ethanol and Biodiesel.
ETHANOL: is an alcohol, made by fermenting biomass that is high in carbs, like corn. The process in which this is done is similar to brewing beer. It is added to vehicle fuels to cut down on harmful emissions like CO2.
BIODIESEL: is made using vegetable oils, animal fats, algae, or recycled cooking greases. It can be used as a diesel additive to reduce vehicle emissions or in its pure form to fuel a vehicle. There are even converters that can be installed into existing vehicles that allow them to run on this fuel.


You may be thinking that this is not a very viable option but the Department of Energy states that we could produce four percent of our transportation fuels from biomass by 2010, and as much as 20 percent by 2030. And as for electricity, the U.S. Department of Energy (DOE) estimates that energy crops and crop residues alone could supply as much as much as 14 percent of our power needs.



In fact, the father of a personal friend of mine develops biodiesel in his own back yard! I talked to him and got the scoop on how he does this:
The process includes some very common household items and then again some not so common, but attainable. He begins by collecting the used grease from local restaurants. On each collection run he estimates gaining about 100 gallons of used grease. The first step of the process is to clean the grease thoroughly and get out all the “crud” from the restaurant grease as possible i.e. bits of food, etc. He does so by using a very large pair of pantyhose and coffee cans. He pours the grease through the pantyhose into the coffee can. He repeats this process so in the end he has strained the oil through the pantyhose twice. He then moves this to a larger container and mixes with methanol and lye which are both toxic so it is extremely important to be careful. These chemicals are obtained from chemical warehouses and require special permits to transport. The chemicals mix with the grease and break down the fatty acids in the vegetable oil so much so that it changes the chemical composition of the oil. You then let the mixture sit for 24 hours and all the fat separates from the oil in the bottom of the tank like a thick sludge. The sludge gets thrown away in a special container at the dump. You then use water to wash the oil you have from the reaction. This removes the chemicals and fat. Then it gets drained off and the rest of the product is able to be burned in order to heat your home or fuel a biodiesel car. Out of a 50 gallon tank of raw restaurant oil he reports that he is able to use about 45 gallons to heat his home directly. The amount he makes from one run heats his large home for about 15-20 days. You should not try this process at home unless you have more knowledge than I have provided about it. Certain steps are very dangerous such as the use of toxic chemicals. Because of this only someone who deals with these substances professionally should only conduct it.

8 Awesome Uses of Wind and Solar

This website has some really cool gadgets and other things that are powered using wind and solar. When it comes to cutting down on the use of fossil fuels, every little bit helps! :p

Check them out here!

Welkommen!

Hey all! Welcome to Purge Our Planet (POP). In today's world we're trapped in an oil-ocracy! As Thomas Friedman would put it.. a "petro-dictatorship". The population is going to keep growing and the need for oil is not going to slow down. That is unless... We make Alternative Energy available, appealing and affordable to the masses. This blog is going to supply a wealth of information to make the pros and cons of different forms of alternative energy (i.e. wind, solar, hydro, geothermal, biofuel, etc) known to the average joe. If there is a higher demand to have these things become available we could "be the change we wish to see in the world" (Ghandi), but first we need to know about them! POP is the perfect place to start.
