Wind Energy Pros - 0 views

  • Cons of Wind Energy Wind is highly variable. Wind speed varies by numerous factors, including weather, location and season, so not all places are appropriate for wind energy. At Inn Serendipity, we rarely overproduce electricity during the summer months. Equipment requires a sizeable upfront investment, depending on the size of system selected. To meet the needs of a modest hobby farm, like ours (after energy conservation and efficiency efforts have been exhausted), a 10 kW system that costs $40,000 to $70,000 would be needed to become a net producer of electricity on an annual basis. Evaluating projected wind-system output is difficult due to variability of turbine design and production conditions. “Wind turbines are not created equally,” Hippensteel says. “Some require considerably more maintenance and service than others.” Living with a renewable energy system demands a more energy-mindful way of living. After any big storm, we check our inverters in much the same way that our farmer neighbors check on their animals. State or municipal zoning laws may result in expensive hearings or possibly prevent you from erecting a tower of sufficient height. NIMBYism: Some neighbors may voice objections to the sight or sound of a swishing turbine. While possible harm may be done to birds, research studies, such as one by the National Wind Coordinating Committee, have found that collisions with windows in buildings and vehicles, capture by outdoor cats, as well as poisoning due to chemicals cause far more avian fatalities than encounters with residential wind systems. Depending on location, securing capable technicians or service workers for possible repair or maintenance can add significant costs to owning a system.

    "Pros of Wind Energy Wind is renewable, freely available and tax-free. Farm businesses may even be eligible to receive a wind-production tax credit. No pollution or waste is generated by the system's operation. Depending on the wind turbine selected, the equipment can be low-maintenance. In general, the more complex the system and the moving parts, the more likely repairs or maintenance will be needed. (Note: After five years, our 10 kW Bergey's generator and inverter required no special repair.) A growing number of utility companies offer simple net metering contracts. (More than 40 states have net metering according to the Database of State Incentives for Renewables and Efficiency.) Under net metering, a wind energy system owner would receive credit for at least a portion of the electricity they generate. There are numerous statewide wind-energy financial incentives, according to Database of State Incentives for Renewables and Efficiency. Numerous national manufacturers of wind turbines have proven reliability track records, including Bergey, Proven, Abundant Renewable Energy, Wind Turbine Industries Corp., and Southwest Windpower, according to John Hippensteel, and engineer with Lake Michigan Wind and Sun, Ltd. Land within the acre or two needed for a residential wind turbine can still be used for pasture, gardens or other agricultural purposes. In our experience-as as noted by the American Wind Energy Association, the Midwest Renewable Energy Association and others-as of 2009, wind is the most cost-effective source of renewable energy, especially when compared to solar electric (photovoltaic) systems. Depending on the system and electricity rates, which continue to rise, your investment might break even in about 17 years."

Advantages and Disadvantages of Solar Energy - 0 views

  •  
    "Advantages of Solar Power? Solar energy is a clean and renewable energy source. Once a solar panel is installed, solar energy can be produced free of charge. Solar energy will last forever whereas it is estimated that the world's oil reserves will last for 30 to 40 years. Solar energy causes no pollution. Solar cells make absolutely no noise at all. On the other hand, the giant machines utilized for pumping oil are extremely noisy and therefore very impractical. Very little maintenance is needed to keep solar cells running. There are no moving parts in a solar cell which makes it impossible to really damage them. In the long term, there can be a high return on investment due to the amount of free energy a solar panel can produce, it is estimated that the average household will see 50% of their energy coming in from solar panels.   Disadvantages of Solar Power? Solar panels can be expensive to install resulting in a time-lag of many years for savings on energy bills to match initial investments. Electricity generation depends entirely on a countries exposure to sunlight; this could be limited by a countries climate. Solar power stations do not match the power output of similar sized conventional power stations; they can also be very expensive to build. Solar power is used to charge batteries so that solar powered devices can be used at night. The batteries can often be large and heavy, taking up space and needing to be replaced from time to time."

    "The Future of Wind Energy Wind energy is a clean, renewable way of producing electricity. If costs are brought down, its future looks assured as a complement to other electrical production technologies such as fossil fuels, nuclear energy, and solar energy. Much of its future development will undoubtedly be offshore."

    "Energy is vital to our daily lives. It helps us produce food, fuel transport and power communication channels across the world. Over the coming decades, more people will gain access to energy and enjoy higher standards of living. But these developments could place greater pressure on our world's resources, such as energy, fresh water and food. At the same time, climate change remains a serious concern. At Shell, we use human ingenuity, innovation and technology to unlock the energy our customers need to power their lives in the years ahead, while aiming to limit our impact on the environment."

Kardashev scale - Wikipedia, the free encyclopedia - 0 views

    Kaku mentions the three different types of civilizatio a lot through out his book. Here are definitions for each civilizations. In 1964, Kardashev defined three levels of civilizations, based on the order of magnitude of power available to them: Type I "Technological level close to the level presently attained on earth, with energy consumption at ≈4×1019 erg/sec[1] (4 × 1012 watts.) Guillermo A. Lemarchand stated this as "A level near contemporary terrestrial civilization with an energy capability equivalent to the solar insolation on Earth, between 1016 and 1017 watts."[2] Type II "A civilization capable of harnessing the energy radiated by its own star (for example, the stage of successful construction of a Dyson sphere), with energy consumption at ≈4×1033 erg/sec.[1] Lemarchand stated this as "A civilization capable of utilizing and channeling the entire radiation output of its star. The energy utilization would then be comparable to the luminosity of our Sun, about 4 × 1026 watts."[2] Type III "A civilization in possession of energy on the scale of its own galaxy, with energy consumption at ≈4×1044 erg/sec."[1] Lemarchand stated this as "A civilization with access to the power comparable to the luminosity of the entire Milky Way galaxy, about 4 × 1037 Watts."[2]"
