An Overview of Solar Cells Through The Years

When solar cells first came on the scene in the 1950s, they were simple. Now, there are a wide variety of cells and more are coming as technology improves. An Overview of Solar Cells Through The Years Solar cells are the basic component of any active system used to convert sunlight into a form of energy. Traditionally, solar cells were used as the key part of panel systems that generated electricity or heat for homes. These days, the technology is used in a wide variety of applications, which m

Cooking With The Power of the Sun

Many people understand the concept of passive solar for heating a home. Fewer realize it can be used in to cook food and sterilize water. Cooking With The Power of the Sun A solar oven is pretty much what it sounds like. It is used to cook food and sterilize water. Most people do not even know they exist, but they are an effective way to cook from both an economic and efficiency point of view. The basic idea with a solar cooking is to create a box like structure that the sun heats up dramatical

Attracting Birds To Your Garden

Firstly, birds will be attracted by the geographic location of your garden. To find out which birds are in the geographic area of your garden at the moment, you will have to consult specialty magazines and documentations. Maybe even the weather guy can provide some information regarding this aspect although this is not always true. Libraries and book stores have books based on migration, on the roads that some bird species take to get to their summer or winter residence. Also, taking pictures o

Fighting Plant Enemies

The devices and implements used for fighting plant enemies are of two sorts: (1) those used to afford mechanical protection to the plants; (2) those used to apply insecticides and fungicides. Of the first the most useful is the covered frame. It consists usually of a wooden box, some eighteen inches to two feet square and about eight high, covered with glass, protecting cloth, mosquito netting or mosquito wire. The first two coverings have, of course, the additional advantage of retaining heat

Hydropower As An Energy Platform

Much like solar and wind power, hydropower has been a constant energy source for man. Following is an overview of hydropower. Hydropower As An Energy Platform Hydropower can be defined simply as using the energy of flowing water to generate power. With early man, this power was experienced in the form of propulsion as in moving wheels to grind food materials. With modern man, hydropower is used to turn turbines that produce electricity. In cases such as the Three Gorges Dam in China, this plat

Animals and The Melting Arctic Ice Cap

The arguments for global warming can sound a bit vacuous when discussing temperature changes of only one degree. The impact of the melting Arctic ice cap on animals is much more tangible. Animals and The Melting Arctic Ice Cap There is little dispute that the Arctic ice cap is melting. Since 1979, it has definitively shrunk by 20 percent. The issue amongst most people debating global warming is whether this is because of global warming or just a natural cycle of the planet. From a common sens

Wind Farms ?Limitations as Energy Platforms

As modern society searches around for alternative energy sources, wind farms are getting mention. There are, however, limitations regarding wind farms as major energy alternatives. Wind Farms 鈥?Limitations as Energy Platforms Wind power is an enticing energy platform compared to fossil fuels. The process works by using the inherent energy in wind as a method for producing electricity. The actual methodology is much like hydropower, but with wind used in place of water. Wind turbines catch th

An Overview of Nuclear Energy

In the effort to get away from our oil and coal dependency, nuclear energy is getting attention again. Here is an overview of nuclear energy. An Overview of Nuclear Energy Harnessing a chemical reaction at the nuclear level of certain materials produces nuclear energy. The process is known as nuclear fission. Nuclear fission occurs when certain materials, such as uranium, are manipulated in a manner that causes them to decay quickly. A byproduct of this decal is immense amounts of heat. The h

An Overview of Wind Farms As An Energy Source

With energy issues becoming a daily subject in the news, wind energy is gaining notoriety. Here is an overview of wind farms and their potential. An Overview of Wind Farms A wind farm is simply a collection of wind turbines in a location used to produce electricity. Wind farms can be found in the United States, but are far more prevalent in Europe. China is also beginning to invest large amounts of resources in wind farms as its energy needs grow. The fundamentals of electricity production t
