What are two advantages of using energy-efficient light bulbs?
The benefits of energy-saving light bulbs. Incandescent and inefficient halogen light bulbs are being gradually phased out of the market, with energy saving bulbs stepping up to the plate. This new generation of light bulbs shine brighter, last longer, and reduce the amount of energy that’s required to power them.
What is one disadvantage of becoming more energy-efficient?
Explanation: The most common hurdle for energy efficiency measures to get over is the cost of implementing a new more efficient technology. … However, you will save energy costs over the long-term and this is called “the pay back” period.
Why are light bulbs not energy-efficient?
These light globes work by using a lot of energy to heat the filament to such a high temperature that it glows and gives off light. But only about 10% of that energy is converted into light, making them extremely energy inefficient. So, there’s really no such thing as energy-efficient incandescent light bulbs.
What are the disadvantages of natural light?
The main disadvantage of natural light is it gives the user less control over the lighting options. Too much natural light can leave unwanted glare or harsh shadows on the subject being photographed or filmed. Too little natural light will not give the subject enough illumination.
What is the major disadvantage of LED lights?
Over-driving the LED in high ambient temperatures may result in overheating of the LED package, eventually leading to device failure. … High initial price: LEDs are currently more expensive, price per lumen, on an initial capital cost basis, than most conventional lighting technologies.
What are the benefits of energy efficient lighting?
Benefits to governments include reduced fiscal deficits, reduced public expenditures, reduced energy price volatility, and improved energy security. In terms of the benefits to the local environment, energy-efficient lighting initiatives can help to reduce both local environmental pollution and global GHG emissions.
Why energy efficient light bulbs are better?
Energy-saving light bulbs cost more initially, but they save you more money in the long run because they’re longer-lasting and they burn through less electricity when in use. You’ll also be reducing your negative impact on the environment and living under more natural-like light.
What are the benefits and disadvantages of energy efficiency?
Pros include less use of energy and generally less greenhouse gases, while the cons are increased cost.
What are the disadvantages of energy conservation?
Disadvantages of Renewable Energy

Why is energy efficiency a problem?
Recent estimates and case studies have suggested that in many energy-intensive sectors of developing economies, energy-saving technologies may backfire, meaning that increased energy consumption associated with lower energy costs because of higher efficiency may in fact result in higher energy consumption than there …
