Green Power Options Are The Future Of Energy

Our thirst for oil and other fossil fuels has brought us to the point where we are doing irreversible harm to our planet. We are also quickly realizing that we are running out of these non renewable resources. As the global economy continues to grow, a world fueled by green power is not far off.

As various green technologies continue to be developed, a few of them are already showing promise as serious contenders.

Green power has been around for a very long time, in fact windmills alone go far back in history. Only until recently have these innovative sources of power been taken seriously. Now, as more money is being invested into research, green power sources are being developed that will eventually contribute to how we fuel our need for energy.

One of the most cost effective ways of producing electricity is through the creation of wind farms. Windmills have been sources of power for hundreds of years, but only recently have they been seen as a reliable and stable source of power. Only three percent of the world’s power is supplied by wind turbines, but that number is growing exponentially as people discover how green this power source really is.

Wind technology is easy to manufacturer and install, and once in operation, they are also very easy to maintain. They provide the most effective way of producing energy next to burning coal. As long as the wind is blowing, the turbines will be spinning. They generate nearly as much power as coal, without any of the harmful carbon emissions being released into the atmosphere. Wind technology is the single best candidate to provide a large percentage of our power needs in the future.

On the subject of turbines, another trend emerging is building sea turbines that capture the energy of water currents to generate power. This technology is being used in small scale situations all over the globe, and they are also generating power with no emissions. They are a little more complex than wind turbines, and they require more maintenance due to the corrosive nature of salt water.

Solar power is making a resurgence as a great renewable source of energy, however solar panels are still not cheap enough to be cost effective for general use. But, the great advantage of solar panels is how they only need sun to generate electricity, also with no emissions. There are huge solar farms found in the western United States, among other unpopulated areas in the world, and they are making a significant contribution. As solar technology develops, perhaps this source of power will be more widely used.

Since coal and natural gas are non renewable sources of energy, we cannot count on their availability for the long term power needs we share. Natural gas is a great and clean burning source of energy, but also very dangerous. Methane gas from decomposing matter in landfills burn the same as natural gas, and they are being developed and expanded to help fuel our power supply. Huge underwater pockets of methane have also been discovered all over the planet, and will be in use within the next twenty years or so.

Green power has exploded into the world stage in the recent past, and it will continue to become more and more integrated into our power hungry lives. More research will reveal how these technologies can be adapted to satisfy our ever increasing hunger for power.

Global Warming, Should You Care?

Global warming is a hard fact that probably none of us would wish to deal with. But let’s face it, it is real and it is happening at a pace neither one of us can comprehend and control. With the increase in temperature over the years, it’s no wonder that ice are melting over at North and South pole. But there are many things about global climate changes that are still unknown to us, what we do know is that if this continue, inevitably human race will be wiped off from the face of the earth.

Exactly what are the dangers of it?

Melting of ice over at each end of our poles does not only affects animals living there. It has a global effect in which sea level will rise, as well as the temperatures. When that happen, animals either lose their habitat, or are unable to cope with the sudden change in temperature and thus will be extinct. Food chains will also be disturbed, given that we humans depend a lot on our marine life to keep the balance in check, it will not be a pretty scene.

Do bear in mind that with the rise in sea levels will means some low land island and countries will be covered in water in no time if something is not being done to combat it. As of now, many have reported that the country is sinking at an alarm rate and very soon it will be submerged.

Severe hurricanes and thunderstorms are also predicted to happen as a result of that, and unfortunately not every country or every where are equipped with state of the art technology that can handle and take precaution against such happening, casualties will be inevitable.

A change in our climate and temperature will also means development of newer and more lethal bacteria that we might not be able to keep up and find a cure faster than the rate it might evolved. More outbreaks will happen and more lives will be claimed.

With the rise in temperature, do not be surprise to see a shortage of crops, this is because higher temperature will means more rain and less snow, which certain crops will not be able to thrive under such harsh condition.

Global warming is without a doubt, a real life scenario that are caused by human activities. Release of carbon monoxide into the atmosphere have picked up since the 1970s and we have seen some of our worst disaster happened since then. Therefore, we should definitely do what we can and afford, by cutting down emission of carbon monoxide and stopping the waste of earth resources, we can make a difference.

Global Warming vs Natural Climate Change

by Janet Corby

Do you ever feel like you know just enough about global warming to be dangerous? Let’s see if we can fill in some of the gaps with the latest info from real global warming experts.

Scientists, together with us environmentalists, are constantly warning politicians that time is running up but that doesn’t seem to bother them, especially now in times of recession. Revive economy or save the planet? Scientists and economists can agree with Buddhist monks and Christian activists that ruthless destruction of natural habitats is evil and careful preservation of birds and butterflies is good. The worldwide community of environmentalists-most of whom are not scientists-holds the moral high ground, and is guiding human societies toward a hopeful future. Scientists are human; they do not wait for proof. Many devote their professional lives to seeking evidence for hypotheses, especially well-funded hypotheses, they’ve chosen to believe.

Temperatures were high at that time due to the peculiarities of the Earth’s orbit. During the Pliocene (2-5Ma) before the Quaternary ice age began, temperatures were also significantly warmer than today. Temperatures have steadily increased at around a quarter of a degree for every 1,000 years. During the last 100 years temperatures have increased by twice that amount.

Think about what you’ve read so far. Does it reinforce what you already know about global warming causes? Or was there something completely new? What about the remaining paragraphs?

Human activities have altered the chemical composition of the atmosphere through the build-up of greenhouse gases – primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed although uncertainties exist about exactly how earth’s climate responds to them. Humans measure warmth as temperature which is a measure of the amount of heat contained in a physical object. One can envision this concept by thinking of a pot on a stove.

Global warming is one of the most hotly debated issues today. Cars have been identified as one of the leading contributors to the escalating global warming problem. Global warming is a huge risk. We’re not just talking about retiring our winter coats in favour of lighter jackets. Global warming is one of those era-defining issues for which perception is reality. And if that perception shifts-and it could shift quickly-the economic impact on energy companies will be swift and lasting.

Global warming had changed their habitat, so to speak. Global warming, as you may already know is the process that describes the earth’s temperature rise. This rise in temperature is because of greenhouse grasses. Global warming and climate change are the biggest problem we are facing today well at least this is what scientists say. There are of course still some that do not believe in global warming and they look at it like some crazy invented thing made by Al Gore and other scientists.

So now you know a little bit about global warming causes. Even if you don’t know everything, you’ve done something worthwhile: you’ve expanded your knowledge.
