Palm Oil as an Alternative Energy

Palm Tree
Palm Tree

Palm oil is currently the most commonly produced vegetable oil in the world. For many rural poor countries, particularly in Southeast Asia, income received from the production of palm oil is the sole source of income.

Palm oil is extremely versatile. While it is extremely high in saturated fats, it is almost solid at room temperature. However when heated, palm oil turns into a liquid. It is used for a variety of purposes, from producing margarine, to a source of alternative energy.

Palm Oil As Biodeisel

Palm oil is used as a fuel in biodiesel internal combustion engines. It is being researched as an alternative to crude oil for its benefits in reducing greenhouse gases and depleting the ozone layer. It is also a renewable source of energy, which means we can always get more; whereas energy sources such as crude oil are finite in their resources.

The Potential of Hydrogen Power for Energy Storage

With oil prices increasing and signs of climate change becoming ever more noticeable, there is much interest these days in alternative fuel sources. On example of such an alternative fuel is hydrogen.

What Experts Know About Hydrogen Power

Hydrogen Fuel Cell

You may think of hydrogen as a fuel source, like gasoline, but it is actually more of an energy storage solution, like a battery. This is because there are not reserves of existing hydrogen that can be mined from the earth. Hydrogen must therefore be produced using another energy source before it can be used. This may make hydrogen sound less useful as a fuel, but energy storage is actually a very important problem.

An Energy Storage Solution

Many clean alternatives for generating power at power stations such as solar and wind are being developed, but without storage solutions this energy cannot be used in places like your car where it must be portable. While batteries can be used for storage, they can be expensive and harmful to the environment. It may be possible to develop a cleaner and less expensive solution using hydrogen.

Natural Gas as a Sustainable, Renewable Energy Source

Natural Gas
Natural Gas

Millions of years ago, the remains of plants and animals decayed and built up in thick layers. This decayed matter from plants and animals is called organic material — it was once alive. Over time, the mud and soil changed to rock, covered the organic material and trapped it beneath the rock.

Pressure and heat changed some of this organic material into coal, some into oil (petroleum), and some into natural gas — tiny bubbles of odorless gas. The main ingredient in natural gas is methane, a gas (or compound) composed of one carbon atom and four hydrogen atoms.

In some places, gas escapes from small gaps in the rocks into the air; then, if there is enough activation energy from lightning or a fire, it burns. When people first saw the flames, they experimented with them and learned they could use them for heat and light.

Reflecting on the Potential of Nuclear Power

Nuclear Power Plant
Nuclear Power Plant

There are over 400 nuclear power reactors that are up and running on the planet, and believe it or not, the number is growing. The whole process of converting uranium into nuclear power is complex, but it all starts off with a mining operation to extract uranium ore. Believe it or not, uranium is not hard to find, it is actually a pretty common element, more common than gold.

Many people don’t realize that our own body houses trace amounts of uranium! Canada’s actually taken advantage of this relatively abundant resource and is so far the number one uranium producer in the world.

The Potential of Wave Power

Wave Power
Wave Power

Experts have been attempting to harness the power of the wave since the late 19th century. As the wind passes over the ocean, it produces waves. There is a direct correlation between the power of the wind and the power of the wave.

Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density. To date there are only a handful of experimental wave generator plants in operation around the world.

The Aguadora Wave Park (AWP) in Portugal is the worlds first commercial wave farm. The AWP produces roughly 2.25 Mega-Watts of power (enough for 1500 homes) and cost just over 8.5 million euros to deploy (though by 2009 costs are expected to exceed 70 million euros).

The Solar Power Timeline

Solar Panels
Solar Panels

What would you do if the utility companies paid you for energy?
You, like me, probably didn’t even know that was possible.

What if you never had to pay energy bills ever again?
Again, something else I didn’t know was possible.

These two questions took me completely by surprise when I started doing research for this article. Especially since both questions pertain to solar power.

The Truth About Solar Efficiency

Everyone has heard about the benefits of solar power in terms of environmental conservation and lessening our dependence on imported fossil fuel. But these are both concepts that apply on a grand scale. It’s very hard to equate what this means to an individual. We have to examine the past, present, and future of solar energy, in order to see that there is huge promise for the future of solar energy.

Wind Power is Part of the Solution for US Energy Needs

Wind Power
Wind Power

Wind power has been an effective energy source for nearly twenty years. At the end of 2007, worldwide capacity of wind-powered generators was over 100 gigawatts. It accounts for upwards of 19% of electricity production in countries like Denmark.

What is Wind Power?

Wind power is the transformation of wind into energy, usually in the form of electricity. Wind technology brought the Nina, Pinta, and Santa Maria to North America in the 1400’s and ran Dutch wind mills, so it is well-established in terms of its potential. Farmers have used wind power to pump water. Human beings have known about the power of wind for a long time and have been using it for thousands of years.

11 Ways to Save Energy and Money by Switching to LED Lighting

LED Light Bulb
LED Light Bulb

Light-emitting diodes (LEDs) are becoming far more common for indoor lighting solutions due to their human and environmental safety, cost, and longevity. An LED is a solid-state semiconductor diode that emits light when an electrical current is applied in the forward direction of the device, as in the simple LED circuit. The effect is a form of electro-luminescence where incoherent and narrow-spectrum light is emitted.

LEDs are widely used as indicator lights on electronic devices and increasingly in higher power applications such as flashlights and area lighting. An LED is usually a small area light source, often with optics added to the chip to shape its radiation pattern and assist in reflection. The color of the emitted light depends on the composition and condition of the semi-conducting material used, and can be infrared, visible, or ultraviolet.

Help America Support A Switch To Clean and Renewable Energy

We Campaign Renewable Clean Energy
Renewable Clean Energy

Global warming is an urgent, but solvable problem. That is why we have joined the We Campaign, a powerful nonpartisan movement of concerned citizens that was founded by Nobel Prize Laureate and former Vice President Al Gore. View more details by clicking the We Campaign banner to the right, or read on to find out how easy and safe it would be to implement a renewable energy solution for America.

Given the tentative speculations that in 10 years oil will no longer be available to us in the quantities we require, we must strive to produce 100% of our electricity via clean and renewable sources by that time. Oil is not the answer and coal is not the answer.

Here are a few reasons we need to move away from coal and oil, and start investing in renewable resources:

  • Even today, half of our electricity is produced by coal rather than oil. OK, but what you may not know is that coal is a top contributer of global warming, and negatively impacts the environment in many other ways. We need to abandon this archaic source of energy for something much cleaner.
  • Even ‘clean coal’ power plants do not prevent carbon molecules from being released into the atmosphere. They are absolutely no help to the global warming / clean environment cause.
  • Early in 2008, Saudi Arabia committed to producing more oil to alleviate high oil prices. OK, but what you may not know is that since that time the price of oil has actually increased. America has no effect at all on the price of oil. We need to relinquish our dependence on it 100%.
  • Wind power is a clean and renewable source of energy. OK, but what you may not know is that the potential for wind power in the US would provide more than 5 times as much electricity as we currently use. In fact, North Dakota alone can provide 33% of the total electricity required by America today.
  • Solar power is another clean and renewable source of energy. OK, but what you may not know is that we can harness enough solar power during the day to provide all the necessary electricity needed to operate at night. In fact, by laying solar panels on a 100 square mile patch of land anywhere in the US (think desert land), solar thermal facilities could provide 100% of our electricity needs, day and night.

So, what does that tell you about clean renewable energy resources? By combining wind power, solar power, and by developing additional alternative energy resources such as Ethanol powered and hybrid vehicles, the US could potentially be free of environmentally and economically damaging sources of power.

Support the Challenge

It will certainly take more than just one man to stand up for this movement. Please do your best to support America in this time of energy crisis. Do it for the Earth, for your kids, for your grandkids, but most of all do it because it’s the right thing to do.

Al Gore just challenged the nation to take bold steps towards solving the climate crisis. Click the banner to view his dramatic speech and to add your vote to the petition. Join the We Campaign and support a movement to more efficient, clean, alternative energy.
