Disadvantages of Alternative Energy

Alternative energy would seem like a good choice for new home builders and people who are in the market to buy a new automobile. There are disadvantages of alternative energy that realistically need to be considered.

One of the biggest disadvantages of alternative energy is that it cannot be stored like coal and natural gas can. Storage is a huge issue because using alternative energy puts us at the whim of Mother Nature. If there is no wind for a week, relying on wind power becomes a problem. If you are too far north, solar panels will only produce sufficient energy when the Northern Hemisphere of the planet is tilted towards the sun and so on.

Energy

Other sources of alternative energy are being studied as well to power not only our homes but our vehicles as well. Hybrid cars have been on the market for a while. They use the same idea as an electric car only they don't need to be plugged in to recharge. They use their braking system to regenerate power and they still have all of the engine power of a gasoline engine. New technologies to produce a fuel cell vehicle are currently underway along with a hydro-powered hybrid using hydrogen.

Another of the disadvantages of alternative energy is that it can be expensive to implement into our already set up infrastructure. Most of the alternative energy resources available today require a different type of wiring system than what we currently have in place. This could cause the transformation to alternative energy sources to be delayed until we have depleted the remaining amounts of fossil fuels found on our Earth today.

Fossil fuels are less expensive right now than alternative energy due to the amount of changes that have to be made to adapt a alternative energy plan. This proves to be another one of the disadvantages of alternative energy. Fossil fuels are readily available and easy to use. They can be transported to almost any location for use. Power plants are already set up for burning fossil fuels like coal and this makes the whole process less expensive than transforming to alternative energy.

The advantages of using alternative energy will be realized when people are forced to make the change if for example, we deplete all of our fossil fuels or the cost of use simply become prohibitive. The disadvantages will slowly fade away as more and more people use alternative energy as their source of power.

Comparison of Diesel and Gasoline Engine, Price, and Efficiency - Advantages and Disadvantages

Some twenty or so years ago, diesel engines were a popular trend among motorists. However, because of the diesel engine's weaknesses in the form of excessive noise, performance unreliability, and pollution-inducing emissions, many drivers have opted to steer clear of the engine type in favor of the petrol gasoline engine. At present, the diesel engine has corrected its errant features and has overcome shortcomings. Because of this, motorists today are faced with the task of comparing the diesel engine and the gasoline engine in an attempt to find out which among the two is better.

The most basic criterion for a car owner is to consider the engine's money-saving features. In this area, the diesel engine fares better. Gasoline engines use fuel and air to create combustion. The diesel engine, on the other hand, relies solely on air compression and can attain combustion all by itself, thus doing away with spark plugs and tune ups. This means that diesel types get better fuel economy because of their self-combustion abilities. The diesel fuel, because of its high fuel density, allows diesel-engine drivers to save twenty to thirty percent in fuel consumption. Furthermore, in terms of fuel price, the diesel fuel is cheaper compared to the gas fuel.

Efficiency

However, when pitted against each other for initial affordability, the gasoline engine easily wins. Diesel engines, by known fact, are much more expensive that the gasoline-run ones. This is probably so because of the diesel engine has a stronger torque power compared to that of a gasoline engine. The former has enough torque to haul heavy equipment and can very easily ascend steep terrains. Because the diesel engine was built to sustain added stress of higher compression and cylinder pressure, diesel engines have a longer road life compared to gasoline engines.

But the diesel engine is not without its quirks and shortcomings. Motorists find the diesel's noisy and rattling run very annoying. Gas engines are far more capable of giving a smooth and relaxed ride as they only vibrate. Gasoline engines perform better in terms of acceleration. Because diesel engines do not have their own spark plugs, it is more difficult to get these engines to start up. This is hard to especially during winter season where the cold weather slows down the rise and combustion of the diesel fuel. There are, however, turbo-diesel variants that are said to deliver quicker acceleration.

On issues concerning engine maintenance, the gasoline engine is more cost-efficient. The diesel engine must get oil changes for at least every 3,000 miles. Compared to the gasoline types, diesel engines need constant and regular check-ups to insure its optimum performance. Gasoline engines require no hassle as they come equipped with their own spark plugs, engine oils, and anti-freeze formulas. And one more thing, because the diesel fuel is refined, diesel fuel is considerably dirtier than its gasoline counterpart. This situation can entail that air and fuel filters be replaced annually. This can ultimately suggest that maintenance-wise, diesel engines can cost more compared to gasoline types.

Environmentally, the diesel engine is the bad-boy in the emission arena. Diesel is less refined, thus, you can expect that its exhausts are not as filtered as that of a gasoline fuel.

Comparing diesel and gasoline engines certainly yield varied results. There is no distinct line that makes one completely superior over the other. The bottom-line really, here, is that choosing an engine type does not merely rest on its fuel-efficiency or road performance alone. There are several factors to consider too. The engine type that a driver chooses must be one that can suit his or her needs. If the motorist is looking for a vehicle that delivers quick acceleration, the gas engine is the logical choice. But if the driver were to require fuel economy, power, and durability, then the diesel engine is the way to go.

Solar Energy Advantages Disadvantages

Many of us know that solar energy is a good thing, but few really understand why. Therefore, I compiled a comprehensive list of solar energy advantages and disadvantages that will enable you to make an educated decision whether on not Solar Power is right for YOU.

Solar Energy Advantages

Energy Efficiency

1. Saves you money

• After the initial investment has been recovered, the energy from the sun is practically FREE.
• The recovery/ payback period for this investment can be very short depending on how much electricity your household uses.
• Financial incentives are available form the government that will reduce your cost.
• If your system produce more energy than you use, your utility company can buy it from you, building up a credit on your account! This is called net metering.
• It will save you money on your electricity bill if you have one at all.
• Solar energy does not require any fuel.
• It's not affected by the supply and demand of fuel and is therefore not subjected to the ever-increasing price of gasoline.
• The savings are immediate and for many years to come.
• The use of solar energy indirectly reduces health costs.

2. Environmentally friendly

• Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment.
• It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulphur dioxide or mercury into the atmosphere like many traditional forms of electrical generations does.
• Therefore Solar Energy does not contribute to global warming, acid rain or smog.
• It actively contributes to the decrease of harmful green house gas emissions.
• It's generated where it is needed.
• By not using any fuel, Solar Energy does not contribute to the cost and problems of the recovery and transportation of fuel or the storage of radioactive waste.

3. Independent/ semi-independent

• Solar Energy can be utilized to offset utility-supplied energy consumption. It does not only reduce your electricity bill, but will also continue to supply your home/ business with electricity in the event of a power outage.
• A Solar Energy system can operate entirely independent, not requiring a connection to a power or gas grid at all. Systems can therefore be installed in remote locations (like holiday log cabins), making it more practical and cost-effective than the supply of utility electricity to a new site.
• The use of Solar Energy reduces our dependence on foreign and/or centralized sources of energy, influenced by natural disasters or international events and so contributes to a sustainable future.
• Solar Energy supports local job and wealth creation, fuelling local economies.

4. Low/ no maintenance

• Solar Energy systems are virtually maintenance free and will last for decades.
• Once installed, there are no recurring costs.
• They operate silently, have no moving parts, do not release offensive smells and do not require you to add any fuel.
• More solar panels can easily be added in the future when your family's needs grow.

Solar Energy Disadvantages

• The initial cost is the main disadvantage of installing a solar energy system, largely because of the high cost of the semi-conducting materials used in building one.
• The cost of solar energy is also high compared to non-renewable utility-supplied electricity. As energy shortages are becoming more common, solar energy is becoming more price-competitive.
• Solar panels require quite a large area for installation to achieve a good level of efficiency.
• The efficiency of the system also relies on the location of the sun, although this problem can be overcome with the installation of certain components.
• The production of solar energy is influenced by the presence of clouds or pollution in the air.
• Similarly, no solar energy will be produced during nighttime although a battery backup system and/or net metering will solve this problem. See http://www.dsireusa.org for details on how net metering allows you to save electricity and money.
• As far as solar powered cars go - their slower speed might not appeal to everyone caught up in today's rat race.
