Affiliate marketing programs has never been as popular before as it is today.  Why?  There can be a number of reasons.  The most probable reason, however, could be the fact that the benefits of affiliate marketing have become clearer to a lot of people now than they were before.
Today, both the merchants and the affiliates can see clearly that affiliate marketing can work for both of them.  The merchant sees affiliate marketing today as the chance to advertise their products at a lower cost.  The affiliates, on the other hand, sees affiliate marketing as an easy way of earning profits online by doing what they like most, and that is by creating websites.
Just as the popularity of affiliate marketing has shifted into greater heights, so has the people's outlook about it changed.  No longer is affiliate marketing considered today as an alternative method for the merchant to advertise his products, or as a source of additional income for the affiliates.  For merchants and affiliates alike, affiliate marketing is now considered as a main source of profits and revenues.
So the question now is what type of affiliate marketing will work best for you?  Are all affiliate marketing programs the same?  Are the benefits the same?  Or are there affiliate marketing programs that work better than the others?

We are currently experiencing an energy crisis and we need to look for alternative energy sources. We need to do more research and development in this area. We need to expand our horizons beyond the fossil fuels and are old ways of being dependent on foreign countries for oil. There are certainly a wide variety of alternatives to these energy sources. Experts believe that the situation is going to get much worse, rather than better so alternative resources for energy need to be explored and put into action as soon as possible.

Wind power can be considered a viable alternative. The use of wind turbines can be developed to progressively use energy efficiently and it is less costly. There are wind farms that are being developed across the world and they are designed to be strategically placed so that they are not damaging the environment particularly birds.

Another viable energy resource is the one that you may not have heard of or considered: solar energy. Solar cells are manufactured which gather and harness the energy given off by the sun and then transmits it into electricity or, into hot water. It is an environmentally friendly resource and does not pollute the atmosphere.

You have probably never heard of ocean wave energy, have you? Experts believe this source of power may have tremendous benefit for the future. Experts believe it has enormous generating potential. France, Ireland and Scotland have successfully been using generators as a source of power for years.

Hydroelectric power can be set up as a powerful generator of electricity and it runs cleanly so there is no potential damage to the environment. However, there are limitations because a large dam cannot be set up anywhere. Small electric generators that are localized have been set up in recently for this reason.

Geothermal energy is another abundant resource. It actually is just below the surface. This type of energy is produced by heating water through the earth's hot molten core. The water then turns to steam, which can be used to keep turbine engines running which converts to electricity. Experts believe there should be extensive research done on geothermal energy tapping.

A substitute for gas can be Ethanol. It can be derived from wheat, sugar cane, strawberries, and even wood and wood cellulose. Experts believe this source of fuel may not be economically feasible as a viable energy source.

Another potential energy source is biodiesel energy. It can be created out of plant oils. There is potential for making biodiesel from soybeans, seeds and other oils. This is a slow and developing energy resource. It may not be economically feasible to use this source of energy on a large scale basis. It is much cleaner than diesel which is oil based.
