Renewable energy has developed clean energy resources and had marketed its usage over the past years. It has always been vague to use sustainable energy to collectively name it when there are various Clean energy resources which are far more abundant than that of oil, coal and natural gas is. But what are these green energy technologies that offer solution to everyday energy consumption? Here are 4 of them for you to know and memorize.

First stop is the Solar panels. People have been familiar to the solar panels for their trusty calculators but a solar panel that could cut down energy costs is something else to see. Renewable energy marketing has introduced solar panels as an efficient way to provide heat for water and homes but that is just the beginning. Photovoltaic panels convert light energy to electricity. It can surely light your homes and make your energy worries lighter. What’s more is that the sun as a sustainable energy source is openly accessible to anyone and everyone. Renewable energy resources should be further explored, such as the sun, to make use of its abundance.

Second would be bio fuels. Leaving the house hold concerns aside, bio fuels are more commonly used to power cars. Unlike conventional fuels, bio fuel is produced from fermented crop products which are high in sugar or from plants that contains high amounts of vegetable oil. Bio fuel has several other usages such as for cooking and heating homes. This technology has just been further develop in more later years than the other technology but it has been so far the most frequently used by normal consumers so far. It is cheaper than the other renewable energy resources. The technology works on converted cars as well as specifically designed ones.

Biomass on the other hand is large with large land owners as well as farmers. Owning a farm means having more than enough fertilizers to come around. Whether it is animal droppings or just unused crops and vegetables, production of biomass to fuel stoves and farms would be a breeze.

Windmills are not just for windy days. Coming in at fourth is the ever loved wind mills or as we call it today, wind turbines. Wind mills are not just for grinding corns and drawing water by the stream, kinetic power from the wind can be easily converted into electricity. Wind turbines are used mostly in European country because of the abundance of space and breeze coming from all direction. One 3.3 km wind turbine can answer any man’s prayer for free energy. Costly, yes, but for those who can afford; wind turbines will save you a lifetime’s worth of electricity bill!

There are actually so many companies providing clean and cost effective means of alternative energy. However most people do not know of them, as they lack exposure, for they do not subscribe to renewable energy marketing services.

Product Description
In STORMS OF MY GRANDCHILDREN, Dr. James Hansen, the nation’s leading scientist on climate issues, speaks out for the first time with the full truth about global warming: the planet is hurtling even more rapidly than previously acknowledged to a climatic point of no return. Although Hansen was Al Gore’s science advisor for “An Inconvenient Truth,” his recent data shows that our situation is even more dire today. But politicians haven’t made the connection between th… More >>

Product Description
The vast majority of scientists agree that human activity has significantly increased greenhouse gases in the atmosphere—most dramatically since the 1970s. In February 2007 the Intergovernmental Panel on Climate Change found that global warming is “unequivocal” and that human-produced carbon dioxide and other greenhouse gases are chiefly to blame, to a certainty of more than 90 percent. Yet global warming skeptics and ill-informed elected officials continue to dis… More >>

What We Know About Climate Change

Truth About Renewable Energy

The curious thing about this reasoning is that averages are phantom numbers that nothing ever depends upon. What matters so far as climate change is concerned is not whether the average temperature of the earth is rising, but whether the temperature at the poles and on mountain tops where glaciers are locates are rising. For if the ice and snow at these places melts away, humanity is in for some difficult times. That a recognized scientist should make a claim based on the unknown average temperature of the earth is dubious at best. Either Mr. Caruba has misunderstood Dr. Gray’s claims or Dr. Gray’s recognition as a prominent scientist is questionable.

That the earth’s average temperature is irrelevant can easily be demonstrated. Consider the following sequence of ten terms: 1, 3, 5, 7, 9, 10, 8, 6, 4, 2. The average of this sequence is 5.5. Now consider this sequence: 3, 3, 5, 7, 8, 9, 7, 6, 4, 3. The average of this sequence is also 5.5. Now suppose the first and last terms in the both sequences represent the temperature at the poles before and after global warming was noticed. Clearly, the temperature at the poles has risen while the average temperature has remained the same. As a matter of fact, it is easy to show that the temperature at the poles can have risen while the average has gone down. Look at this sequence: 3, 2, 4, 6, 8, 9, 7, 5, 4, 3. When this sequence is compared to the first, the terms representing the temperature at the poles have risen but the average had decreased to 5.1. Certainly any reputable scientist would understand enough about averages to have known the point that I have just demonstrated.

Mr. Caruba then writes this: “The IPCC has depended on computer climate models for its claims and there is now a volume of papers demonstrating how they have repeatedly been proven to be inaccurate. As Dr. Gray points out, if you cannot validate these models as actually capable of making predictions, ‘no self-respecting computer engineer would dare to make use of a model for prediction.’”

But think about this for a moment. The National Weather Service uses computer models, absolutely none of which is accurate, to predict the weather. Yet those predictions, while never absolutely accurate are certainly useful. All of us rely on them every day. They tell us when to carry raincoats and umbrellas, when to wear heavier clothing, when to get sanding trucks and snowplows ready, even when to evacuate people from areas threatened by hurricanes. Would it be reasonable for anyone to suggest that we should abandon these predictions because the models “have repeatedly been proven to be inaccurate”?

It has always been a puzzle to me why people who are successful in some intellectual professions such as some branches of the physical sciences and all branches of the social sciences can engage is egregious reasoning when a thesis contradicts their cherished beliefs. Examples of such reasoning are easy to find, especially when the theses these “scientists” find objectionable have economic consequences. The critics of global warming are all worried about the costs of making the societal changes that countering global warming requires, but they refuse to even consider the costs that will be incurred if global warming is real and nothing is done to reduce or stem it. These people, somehow or another, allow ideology to trump reason.

No one knows for sure, of course, what the cause of global warming is. Is global warming caused merely by changes in the earth or the solar system over which we have no control, or is it caused by the huge amount of greenhouse gasses that we have been pumping into the atmosphere? No one knows, but we’d better hope that our practices are at least a major part of the problem, for if they aren’t, life on this planet may be doomed.
