⦁Energy entrepreneur's business strategyBefore you decide to operate either any kinds of secondary energy or primary energy supply business or both kinds of energy supply business. I recommend that you need to consider how to solve these questions before choosing which kind of energy product to manufacture. The questions may include as below: Who are your energy business's competitors (peers)? How do they compare? How have your energy business company performed cyclically? How to choose to manufacture to sell which kinds of primary or secondary energy product(s), either manufactures only primary energy product(s) or manufactures only secondary energy products or both? Which countries do you plan to sell your energy product?Illustration by Wilsey, composition services graphiss showed that these natural resources to energy product the world's electricity percentage, such as below:41% of coal, 5% of oil, 21% of gas, 13% of nuclear, 16% of Hydro, 3% other renewable secondary man-made energy.Hence, coal will be future the major natural resource to produce electricity. The energy entrepreneur ought attempt to explore any coal resources, when who choose to supply electricity power to consumers for future energy consumption country markets.Which is space heating? It means heating the space inside a building. Today, many homes use solar energy for space heating. A passive solar home is designed to let in as much sunlight as possible. It is like a big solar collector. For example, a passive solar home doesn't depend on mechancial equipment, such as pumps and blowers to heat the house, whereas active solar homes do. It seems that future human can attempt to apply solar energy to use in home conveniently.How can apply solar energy? Solar energy can be used to heat water. Heating water for bathing, dishwashing and clothes washing is th second largest have energy cost. Installing a solar water heater can reduce home water heating bill be as much as 50 percent. A solar water heater works a lot like solar space heating. For example, installing a solar collector on a house roof where it can capture sunlight. The sunlight heats water in a tank. The hot water is piped to faucets throughout a house, as it would be with an ordinary water heater.Solar energy can also be used to produce electricity. Two ways to make electricity from solar energy are photovoltaics and solar thermal systems both. However, compared to other ways of making electricity photovoltic systems are expensive. It can cost to 30 cents per kilowats hour to produce efficient from solar cells. Similar to solar cells, solar systms also celled solar power, use solar energy to produce electricity, but in a different way, most solar thermal systems use a solar collector with a mirrored surface to focus sunlight onto a receiver that heats a liquid. However, solar energy has great potential for the future. Solar energy is free, and its supplies are unlimited. It doesn't pollute or otherwise damage the environment. It can't be controlled by any one nation or industry. IF we can improve the technology to harness the sun's power, we may never face energy shortages again.For active solar home example, passive homes can get 30 to 80 percent of the heat, they need from the sun. They store their heat energy by using think walls and building materials that retain heat well like concrete, stone and even water. For solr water heating another example, solar energy can also be used to heat water for household use. Heating water for bathing and washing is the second largest home energy cost. Installing a solar water heater can cut that cost in half. A solar water heater works a lot like solar space heating. The sunlight heats water and stores it in tank. The hot water is piped to faucets throughout a house, such as it would be with an ordinary water heater.
