This is mainly due to the favorable market demand for air transport, even after the 9/11 terrorist attack in the United States and the recent global financial recession. According to the ACI Global Traffic Forecast…

The robust demand for commercial and air transport drives the current intensive research and development of energy efficient planes. As a matter of fact, the modern aircraft today has decreased in energy consumption significantly compared to old planes. According to Ngo and Natowtiz, with occupancy rates on the order of 70-80% the fuel consumption of recently built planes is on the order of 5L/100 km per passenger and that this means flying over a given distance as about the same in terms of energy consumption and CO2 emissions per passenger as driving the same distance with a car.

It must be underscored that technological innovations in the history of mankind, especially in the area of transportations, has been less energy efficient than the technology it replaced. In this regard, the use of supersonic air transport could reverse the trend for air transport. The engine of these supersonic jets are expected to beat all other current aircrafts in the area of energy efficiency because its technological designs optimize such items as fuel/air mixture, engine temperature and airflow velocities. (Siuru 155) A future supersonic transport could travel at speeds of Mach 2.7, making a trip from Los Angeles to Tokyo in a little over three hours. (Siuru 155) Some market projections anticipate a fleet of some 300 to 1,200 commercial supersonic jets in service in the next 10-30 years.
Another interesting area in the supersonic jet technology, which makes it the most energy efficient aircraft of the future, is the so-called oblique-wing airliner concept. It supposedly eliminates the conventional fuselage by having passengers ride inside the wing. Siuru pointed to the computations that show how an oblique-wing airliner could fly at Mach 1.6, twice the speed of the Boeing 747, while consuming no more than a subsonic jumbo jet. Here, the level of fuel efficiency is achieved through the oblique wing’s very high lift-to-drag ratio and, subsequently,

This research aims to evaluate and present a great amount of future technology. Technology can enrich our lives, but it’s the responsibility of the people that make sure it is put to beneficial use. Ultimately, the future will be an exciting place, but we must all work together to ensure that true progress is achieved.
Any economy is driven by energy. Industries rely on electricity and fuel to run their daily production or processing activities. People light and heat their houses using energy. People also cook their meals using fuel. The cars, planes, or trains that people use to get to their respective workplaces require energy.
Many homes currently use a type of solar energy that is not commonly known or promoted commercially to a large portion of the building industry; this is passive solar or climatic design. Passive solar homes range from homes that are heated entirely by the suns’ rays to those that incorporate south-facing windows that provide a small portion of the heating load.
However, using nuclear plants to fulfill the energy needs is not going be cost free, posing a severe threat to environment. Many critics argue that the reasons for the 30-year halt in U.S. nuclear plant were mostly contributed by the higher capital costs.
Apparently, the increase in food demand in the recent years has seen the food-energy relationship enter a new era which could prove fossil resources as an insufficient mode of energy production in the food system. A food system here refers to all the work, research and processes involved in making sure that a population is well fed incorporating a balanced diet.
All scientists are of the opinion that increased use of renewable sources of energy can be one potent solution to this problem. Sustainable development and renewable energy use share an intimate connection. The changes in climate are the topic of the time.
According to the paper the recent economic crisis has destroyed the economy of many developed countries including US and UK, but India and China managed to escape from the crisis without many damages to their economies. The agricultural and industrial growths in these countries are huge. Energy requirements of a country depend on its economic growth.
This phenomenon has triggered a chaos in the minds and hearts of people globally. The race to accumulate resources has forced prices in commodities to sky high. Even basic food items are at their highest. One of the sectors most affected by this
The solution to this problem is alternative energy (LePoire, 2011).
The US government should increase the incentives to attract alternative energy investment. Increase in incentives will increase the alternative energy sources
Being efficient in energy usage can help Tokyo in running its daily operations by using less energy. As a result, resources will last longer and will pollute the air less.
Tokyo is one of the leading megalopolis of the world with over 40million
