I have to “make” a green city and it will use renewable energy source including solar and wind energy. How would I make the wind and solar energy sustainable and not have shortages of power?

Small places, like a remote house or an island, might have batteries. A large place, like a city, would be connected to a "Grid", or electrical energy transmission system. If the wind stopped blowing, deep in the night, they would pull energy off the grid, from a nuclear plant, or coal-burning generation station, or hydroelectric project many miles away. A town on an island might have a large diesel generator.

Solar homes. Many people talk about them, although few in the U.S. do more than talk. They are said to reduce utility bills. Some say a solar home cuts utility bills drastically. Some are able to sell excess power back to the power grid. Savings are not automatic, however. Steps must be taken to make the solar home efficient; to conserve the electricity that is produced.

Ways to conserve solar photovoltaic power in the home must be found. The home owner must actively seek out ways to make those photovoltaic (PV) panels on the roof as efficient as possible. Photovoltaic power is free, but it cannot be generated in unlimited quantities. It is important to take measures to use it to best advantage.

Of all the ways to conserve solar photovoltaic power in the home, the most important is probably replacement of power-gobbling electric appliances. Home lighting can also be changed to conserve solar photovoltaic power (PV power). Finally, power usage can be reduced by making every person in the solar home conscious of conservation methods.

12 Ways to Conserve Solar Photovoltaic Power in the Home

1. Shop for energy-efficient appliances and home electronics for your solar home. Most products in this category carry EnergyGuide labels. These labels give an estimate of the products’ energy consumption or energy efficiency, and show the ratings of similar appliance models. In the U.S., appliances and home electronics that meet strict Department of Energy (DOE) and Environmental Protection Agency (EPA) energy efficiency criteria carry Energy Star labels.

2. Replace an electric water heater in a solar home with an energy-efficient propane or natural gas heater. Connect the new water heater to a solar water heater system. The sun will preheat the water, and the new unit will have less work. Wrap the water heater with thermal wrap to retain heat.

3. Replace the solar home’s electric furnace with an energy-efficient propane or natural gas unit. Install a solar panel air heater to reduce the work load of the new furnace. If you are building a new solar home, consider passive ways to heat the floors and air, further reducing the workload.

4. If the solar home is in a hot, dry climate, use an evaporative cooling unit in place of an electric air conditioner.

5. Check weather stripping around all windows and doors. Seal cracks and openings. Stopping air leakage in and out can improve indoor climate control in every season.

6. Insulate the solar home well. Insulation will keep heat or cool air from escaping. It will also keep outdoor cold or heat from entering readily.

7. Use heavy, insulted drapes and window shades/blinds in the solar home to keep out hot or cold air, making cooling and heating units work more efficiently.

8. A serious solar home owner can save even further by using a solar oven for cooking whenever possible. Especially good in hot climates or summer months, a solar oven will cook food with solar energy, and avoid heating the home. Money is thus saved in two ways.

9. Control of computer usage is another of the many ways to conserve solar photovoltaic power in the home. Monitors should be turned off whenever the computer will not be in use for 20 minutes or more. The CPU and monitor both should be turned off when the unit will not be used for 2 hours or more. Power down or sleep modes should be set.

10. Replace light bulbs with Energy Star qualified compact fluorescent light bulbs. If every U.S. home replaced just one light bulb with one of these bulbs, we would save more than $600 million in annual energy costs. To the solar home owner, such savings are vital.

11. Maximize your use of daylight, turning on lights only when necessary. Use windows to advantage, and install skylights where possible.

12. Landscape your property to block the heat of summer sunlight, permit winter sunlight. Deciduous trees near the solar home will shade windows in the summer, and let warming sunlight through in winter months.

Ways to conserve solar photovoltaic power in the home are not limited to these twelve, but if these alone are used, the increase in efficiency will be tremendous.

There are many different alternative remedies and therapies for cancer. Unfortunately, hardly any of these alternative therapies are backed by solid scientific principles and research. Most are just “snake oil” and sleazy clinics in foreign countries.

There really is an alternative treatment, however, that is backed by solid scientific research dating back several decades. It uses what scientists know about cancer cells to reduce and eliminate any type of cancer in all parts of the body. For decades, scientists have been studying the relationship between sugars and cancer. The findings have been consistent over the years—reducing the sugar glucose in the body reduces cancer growth. Eliminating glucose can, quite simply, eliminate cancer.

This process is scientifically valid because of what is known about cancer cells. Like all the cells in our body, cancer cells use the glucose manufactured from the carbohydrates in our diet for energy. Cancer cells, scientists have discovered, are particularly “greedy” and require a relatively high amount of glucose to function, grow and multiply. Without glucose, they eventually die.

What makes the elimination of glucose from the diet such a valid treatment for cancer has to do with what our body is capable of doing in order to supply the rest of our cells with energy. Unlike cancer cells, the cells that make up the rest of our body can use the energy extracted from lipids or fats for energy. Ketone bodies, or ketones, are produced in the absence of enough carbohydrates in order to power the body’s cells. While healthy cells can use ketones for energy efficiently and safely, cancer cells cannot use them at all. If the diet is changed just right and some simple medications are used in just a few days the cancer cells can be killed.

Scientists understand the process involved to encourage the body to create ketones for energy. Different treatment plans involving diets high in lipids and low in carbohydrates have been tested for use with many different types of ailments. All the results show that cancer is a perfect candidate for responding to this type of plan.

So many people with cancer find themselves at a point where they want to do something proactive to fight their encroaching disease. This scientifically valid treatment plan provides something concrete that cancer sufferers can do to attack their cancer using their body’s own mechanisms for creating an alternative energy source for their healthy cells.

You should learn more about how you can activate your body’s natural processes to create and environment inside your body where cancer cell cannot survive. This alternative therapy is backed by science and is very simple to understand.

Change is a watch word for our planet, and changes have been made that have enhanced the Earth. Scientist are exploring the negative effects of solar energy in order to safely replace the energy sources that we presently use with this form.

Solar energy has the ability to give us cheaper if not free electricity to our homes through the use of solar panels. However, before you jump on the band wagon and go out and try to start this new power trip there are a few things you should know. There are some people who believe there are many negatives to solar power.

Many people believe that thermal solar energy has many health risks when it is used to heat water and the air in their homes. This can happen when it has not been set up properly or the manufacturer made errors when producing it.

If it is unable to store the water properly it can cause fungus and molds to grow making anyone who drinks or uses the water sick. To make sure that this does not happen you can make sure that the units used to store the water have been built from materials that are made to prevent this.

PV solar energy also as health risks that you need to be careful of. PV (photo-voltaic) panels require millions of silicon dioxide in order to be used. That number is lowered when they are exposed to heat. The materials that are released during the refining process will increase the rate of toxicity and can affect your health. This is one of the more serious negatives of solar energy that is responsible for eleven to twenty one deaths per each quadrillion joules of energy that are created.

But do not let this deter you completely. Study up on the different types of solar panels and the negatives as well as the positives. You might find that they are worth it in the end.
