Wind and solar energy , in particular, are touted as the energy sources of the future. But entrepreneurs have tried to harness both for centuries. Their limited utility and obstacles, documented since the 1800s, explain why wind and solar make up just a tiny portion of our energy supply today despite a quarter-century of highly preferential taxpayer and ratepayer subsidy. The problem concerns the vicissitudes of weather, which makes wind and solar inherently unreliable and unsuitable for... Read Full Story

With gas prices on the rise, the race is on for cheap alternative fuel sources, including solar power. The major criticisms against solar power facilities, such as wind farms, are unreliability and inefficiency. Solar power depends on some environmental factors that can’t be controlled by humans so that’s the main reason potential investors are bit anxious. Not only money makes a problem but investments need to be followed by large areas with high and effective sunlight during the day... Read Full Story

Glacial ice is formed from highly compressed snow. In areas of the world where more snow falls each year than can melt or evaporate, the snow builds up and its structure gradually changes. After that, the compressed snow, known as firn is transformed to glacial ice. One of the key facts about gaciers is that around 80 percent of the world’s fresh water is locked up inside glaciers, mostly around the poles (ice sheets on Antarctica and Greenland). When summer temperatures bring about the... Read Full Story

After nuclear catastrophe in Northeastern Japan, that country may have a bit different shaped energy policy investing more in solar power technology, alternative energy of biomass and wind turbines. Previous plan to increase the number of nuclear power plants across the Japanese mainland is very likely to be abandoned paving the way for cleaner and probably much expensive green energy. Now it is questionable if it will be expensive more than damage caused by earthquakes with high Richter... Read Full Story

Here is a list of the 10 strongest earthquakes recorded in the last century, according to their magnitude: May 22, 1960 – Chile – An earthquake measuring 9.5 on the Richter scale struck Santiago and Concepcion, triggering tidal waves and volcanic eruptions. Some 5 000 people were killed and 2 million homeless. March 28, 1964 – Alaska – An earthquake and ensuing tsunami claimed 125 lives and caused about $ 311 million in damage. The quake, measuring 9.2 was felt over a large area of... Read Full Story

If we consider that the total energy consumed worldwide, 85% is non-electric, and consists mostly of fossil fuel applications, foremost among them oil, we understand the magnitude of the task of replacing primary energy sources from fossil fuels, and therefore not renewable, renewable alternatives. For clarification purposes we consider a question of terminology: when we include the electricity or hydrogen from energy sources, we must bear in mind that these are two different sources. On...

Organic traffic or free traffic is very simple to explain, but a bit  harder to implement. Organic traffic comes from the search engines, other sites that link back to your site and from direct access via other online and offline methods. While organic traffic is usually thought of as search engine traffic, as you can see, it can come from other sources as well. In the interest of simplicity, this post will center around how to get a steady flow of visitors from the search engines. There is... Read Full Story

Ecotourism is one of the two fastest growing sectors of the tourism industry. Second one is ethnic tourism. Ethnic tours encounters visitors with the forms of native peoples, cultures and arts. Ecological tourism or ecotourism depends on universal appeal of the wonders of nature and can be potentially a more prospective than ethnic tourism. The main advantage o ecotourism is preserving the environment and natural resources by ecotourists and all other friends of nature. Demand is... Read Full Story
