Nuclear fusion, which is the process that powers the sun, has not yet been harnessed effectively as a source of electric energy on Earth due to challenges in sustaining the extremely high temperatures and pressures required for the reaction to occur. Scientists are still researching and developing techniques to make nuclear fusion a viable and practical energy source.
Scientists have struggled to effectively harness nuclear fusion as a source of electrical energy. Despite its potential for producing large amounts of clean energy, controlling the fusion reactions to generate electricity in a sustainable and cost-effective manner has remained a significant challenge.
Nuclear power is sometimes considered a last resort energy source due to its high capital costs, complex infrastructure requirements, and safety concerns. It is generally used when other sources of energy are inadequate or unable to meet the demand.
When energy is unable to pass from a system to the surroundings, it is called an isolated system. In an isolated system, energy is conserved, and no energy can enter or leave the system.
Energy is unable to transfer directly in the form of heat between two objects that are not in physical contact with each other.
First of all, that's not entirely true. It is only when heat energy is uniformly spread out (different objects have the same temperature) that it is unusable. If heat is concentrated in one place, part of the energy can still be used.It is a fundamental law in our Universe, that there are irreversible processes. The reason for this is hard to understand, but scientists have a measure for this, a rather abstract quantity called "entropy" - and the way it is defined, entropy will always increase in any process (or, in the borderline case, not change, or hardly change) - but it can never decrease. It has been found by experience, and by many thought experiments, that no such process exists.

People are heterotrophic organisms. They are unable to manufacture their own food and must obtain their nutrients and energy source from external sources.
No he is unable to travel on and electric train, he prefers to walk.

Dextrose is a simple sugar, also known as glucose, that is a primary source of energy for living organisms. It is a monosaccharide, meaning it consists of a single sugar molecule. Dextrose is commonly used in food products as a sweetener and in medical settings as a source of rapidly available energy, such as in intravenous fluids for patients who are unable to eat.

As lettuce's molecular structure is mainly made up of water (H2O), humans are unable to obtain energy, nor vitamins and nutrients from that source of food. As well as being made up of mainly water, lettuce, is a plant of cellulase. Therefore, humans need a more adequate source of food to help the body maintain its energy levels

The giraffe is the tallest of all living animals; however, scientists are unable to explain the origins of its long neck. (sorry, the first sentence was awful)
If there is no ATP (adenosine triphosphate), cells are unable to carry out essential energy-requiring processes, leading to a shutdown of cellular activities. This could result in cell death and ultimately, organism death due to the inability to generate energy for vital functions.
