What are conventional energy source dicuss?

Conventional sources of energy are the ones that are commonly used, and generally, non-renewable sources of energy, which have been used for a long time.

Convert GWh to MW?

1 gigawatt = 1000 megawatts 1 MW of electricical Power means different GWh in a year according to how long the power can be used through the year. 1 year = 8760 hours. So at 100%, a power plant of 1 MW will produce 8760 MWh, ie 8,76 GWh For instance, with a nuclear power plant that usually runs 80% of the time you have: 1 MW -> 7 GWh in a year You have approximately the same ratio (a bit more) with a thermal power plant (fossil fuel) With wind power plant, they usually run 23% of the time in windy areas (due to meterological conditions). You then have in such a case : 1 MW -> 2 GWh in a year For solar power it is less and up to areas. In California, 1 MW -> 1,4 GWh in a year

In Germany, 1 MW -> 0,6 GWh in a year Electrical power of plants are up to types of plants: Nuclear & Fuel : around 1000 MW (up to power plant size...)

1 Wind turbine : up to 5 MW

Solar plant (photovoltaic) : up to 20 MW

Solar plant (other, experimental) : up to 500 MW so far

Will solar energy continue for America in the future?

Yes, solar energy is expected to continue to grow in America due to decreasing costs, increasing efficiency of solar technology, and rising concerns about climate change. Federal and state incentives are also helping to drive adoption of solar energy across the country.

What energy source does the ISS run on?

The International Space Station (ISS) primarily runs on solar power. It uses large solar arrays to collect and convert sunlight into electricity to power its systems and instruments.

What makes science so important?

Science is important because it helps us understand the world around us, make informed decisions, and solve complex problems. It also drives innovation and technological advancements that improve our quality of life. Additionally, scientific research contributes to our understanding of natural phenomena and the universe.

Is the moon the chief source of radiant energy?

No. The light we receive from the moon is reflected energy from the sun.

The moon has very little radiant energy. All bodies above absolute zero radiate some energy, in the case of the moon it is a very small amount.

How do animals use solar energy?

Animals do not directly use solar energy for energy production like plants do through photosynthesis. However, animals indirectly benefit from solar energy by consuming plants and animals that have derived their energy from the sun. Additionally, animals may utilize sunlight for activities such as basking to regulate body temperature or synchronize their biological rhythms.

How can the sun be used as an energy source?

The sun can be used as an energy source through solar panels, which capture sunlight and convert it into electricity. This renewable energy source is sustainable, reduces reliance on fossil fuels, and is environmentally friendly. Solar power can be used in homes, businesses, and even on a larger scale to power cities.

Is the sun your most important energy resource?

Yes, the sun is a crucial energy resource for Earth as it provides sunlight that is converted into solar energy through various technologies like solar panels. However, there are also other important energy resources like wind, hydroelectric, and geothermal energy sources that can contribute to a diverse and sustainable energy mix.

Does the atmosphere absorb a lot of energy directly from the sun?

No, most of the sun's energy that reaches the Earth's atmosphere is absorbed by the surface of the Earth. The atmosphere does absorb some of the energy but it is relatively small compared to the energy absorbed by the Earth's surface.

Can solar energy can be used up?

No, solar energy cannot be used up because it is a renewable source of energy. The sun continuously emits energy that can be harnessed through solar panels to generate electricity without depleting the sun's energy.

What do the sun and a light bulb have in common?

They both give off heat and light (fluorescent bulbs give off considerably less heat than incandescent bulbs), and most of the heat is "wasted" in that it is not used for any productive purpose.

What is the difference between daily energy requirement and basal energy requirement?

Basal energy requirement refers to the amount of energy needed to maintain basic physiological functions at rest, while daily energy requirement includes the additional energy needed for physical activity and other daily tasks. Basal energy requirement makes up the majority of daily energy expenditure, with physical activity level influencing the total daily energy requirement.

Are changes in solar energy that create day and night the result of earth's rotation?

Yes, changes in solar energy that create day and night are the result of the Earth's rotation. As the Earth spins on its axis, different parts of the planet are either facing towards or away from the Sun, causing the cycle of day and night to occur.

What does the word solar mean in the word solar system?

The word solar in "solar system" refers to our sun, which is a star at the center of our planetary system. The term "solar" derives from the Latin word for sun, "sol."

Is the density of water more than the density of hydrogen sulfide?

Yes, the density of water is higher than the density of hydrogen sulfide. Water has a density of 1 g/cm³ at standard temperature and pressure, while hydrogen sulfide has a density of 1.539 g/cm³ under the same conditions.

What is the central portion of a star called that produces energy through nuclear reactions?

The central portion of a star where nuclear reactions occur is called the core. In the core, hydrogen atoms fuse together to form helium, releasing energy in the process. This energy production through nuclear fusion is what allows stars to shine and emit light and heat.

Why is sound energy kinetic energy?

Sound energy is considered kinetic energy because it is a form of energy associated with the movement of particles. In sound, energy is transferred through the vibration of molecules in a medium, such as air or water. This motion of particles constitutes kinetic energy, which is the energy of motion.

What is the genesis of color?

Color is the result of the interaction between light, an object, and our eyes. When light strikes an object, the object absorbs certain wavelengths of light and reflects others, which our eyes perceive as color. This perception of color is a complex biological and psychological process that allows us to differentiate between different wavelengths of light.

Are fossils examples of organic matter and why?

Yes, fossils are examples of organic matter because they are the preserved remains or traces of once-living organisms. Fossils can include bones, shells, teeth, and other organic materials that have undergone a process of mineralization or replacement with inorganic materials to become stone-like structures.

How does the sun release tremendory amount of energy?

The sun releases a tremendous amount of energy through nuclear fusion in its core. This process involves hydrogen atoms fusing together to form helium, releasing vast amounts of energy in the form of light and heat. The energy produced in the sun's core is equivalent to millions of nuclear explosions happening every second.

What provides the energy to break the connection between actin and myosin?

ATP provides the energy required to break the connection between actin and myosin during muscle contraction. ATP binds to myosin, leading to a conformational change that allows the myosin head to detach from actin.

Can window awnings help save energy and cut down on electricity costs in the summer?

Yes, window awnings can help save energy and reduce electricity costs in the summer by shading windows from direct sunlight, which can lower indoor temperatures and decrease the need for air conditioning. The awnings can also help protect furnishings from sun damage and reduce glare.

What happens when pontential energy ins't completely converted to kinetic energy?
