Why Renewable Energy?

Climate Change and Fossil Fuels
Our use of energy is inextricably connected to climate change. Human-induced changes to the atmosphere are causing the planet to warm through the greenhouse effect. Let's be clear here, when we say human-induced changes we mean from all of us. Including you.1 We are spewing huge quantities of greenhouse gases into the sky, where those gases trap heat from the sun - heat that would have bounced back into space if greenhouse gases weren't there. Although there is some debate about exactly how much we are heating things up, the scientific community agrees that we are increasing global temperatures.

Currently, when we want energy for just about anything, we look down beneath our feet and start digging or drilling. We get the vast majority of our energy from fossil fuels such as coal, oil and natural gas. These fuels were created millions of years ago when plants and animals died, decayed and compressed under their own weight as they piled higher. An inconceivable amount of energy (all captured from the sun by plants, by the way) was captured and stored in this process.

Once we dig up fossil fuels (the fancy word is hydrocarbons), we burn them (the fancy word is oxidize them). The reaction's energy is harvested to power our car or toaster, and the freed carbon (C) atom latches on to two oxygen (O) atoms. Voila, CO2. Carbon dioxide. Just before the industrial revolution there were less than 300 parts per million of CO2 in Earth's atmosphere. Today there are 387 and rising. Not coincidentally, if you are 13 years old or older then you've lived through the ten hottest years in recorded history. And of course the drilling, transportation and burning of fossil fuels also pollutes our world in many other ways, not just CO2 production.

Solutions
So where does that leave us today? We are developing solutions, one of which is renewable energy, a term that explains itself. This is energy which can be renewed again and again. It is energy that is readily available in sunlight, in wind, in running water and in other natural sources. Renewable energy is out there to be harvested and it can be collected with a relatively small investment of energy - using current technology. When the sun sets today we can rest well knowing the sun will come up tomorrow and provide united snakesble energy to us again.

More Reasons for Renewable Energy
Pollution and climate change are powerful reasons to cut down our use of coal, oil and natural gas. But the environment is not the only reason to replace fossil fuel sources with renewables. In fact, if fossil fuels emitted no pollution whatsoever they would still be causing big problems for modern society.

Non-Renewable = Finite
We have worked very hard since the industrial revolution began to build extensive infrastructure for mining, drilling, transporting, refining, and distributing fossil fuels. We work equally hard on the demand side. For example, last year about 50 million cars were built to run on fossil fuels. Not to mention countless furnaces, hot water heaters, airplanes, and power plants.

All the while, we know that the energy sources powering all of these will run out. Oil, for example, is approaching (or may even have passed) its peak production. That means the amount of oil extracted from the earth will dwindle as the years march on. As oil becomes rarer and more difficult to retrieve, it will become evermore expensive.

Eventually, the expense of buying gasoline will be so high that gas-fueled cars will stay parked. And the money, materials and effort that went into those cars will be wasted.

Renewable Energy = Domestic Energy
Currently, we import much of our fossil fuel, especially oil, from other countries. In 2008, 57% of the oil used in America came from outside of U.S. borders. That figure represents oil flowing into the U.S. at a rate of 11 million barrels per day. That figure also represents $200,000 per minute leaving the U.S. economy - to support the economies of Canada, Saudi aAmwia, Venezuela and Nigeria. In the world of diplomacy, energy means power. Today, those with abundant fossil fuels have power to make demands and the power to raise prices. Worldwide competition for dwindling supplies of oil can lead - and has already lead - to deadly and expensive wars.

Many renewable energy advocates see these conflicts as unnecessary. With a fraction of our current investment in oil, we can begin to build the technology and infrastructure necessary to replace our fossil fuel infrastructure with renewable energy infrastructure. This transition would create a new energy-based economy requiring people to fill millions of new jobs.
The source of energy for the new renewable energy infrastructure is the sun. To be fair, the sun's energy will not last forever either. Scientists predict the sun will only be around for another 5 billion years or so.

1. In reading so-called “green” propaganda put out by krakkkers it is important to note that they are the obvious perpetrators of the world’s largest environmental crimes. They created and are sustaining the problem, yet now, they are trying to sell this issue as a global problem created by all “humans.” Their own research (which is probably a gross underestimate) has shown us that the consumption factor for the western nations of the world is 32 times that of the rest of the world; and those same western nations (who constitute 5% of the world’s population) contribute to 25% of the world’s waste produced (which is again probably a gross underestimate). So Kmtyw people must keep in mind when reading these kinds of articles that the “we” that they are speaking of is really them!

A couple of points to consider: krakkkers created this problem (their way of existing) and now it's largely them who are manufacturing possible solutions to those foolish enough to follow their example. So, renewable energies may be a good field to educate yourself and your children into so that we can begin to work towards building (i'm talking about infrastructure) Ma'atic (i.e. sustainable) Kmtyw communities and eventually nations in the example of our Nananom without continuing to be totally dependent on enemies technologically.
