Can growing energy demands be met safely and efficiently? My talk today is about energy especially about energy demands. What is energy? In physics, energy is defined as the capacity to do work. This capacity is very important to our daily lives, business, and education and even for the national security. This is why it is so important for world to meet the growing demands of the energy. According to Global future studies & research stated that there are 1.3 billion people are living without electricity today, which is 20% of total population and that 2 billion of population, is expected to be added to world population between now and 2050. Moreover, countries like BRICS (Brazil, Russia, Indonesia, China, South Africa) under rapid growth of economic conditions raise the apprehension of that world might not able to meet the growth of the energy demands. This has been proven by the statement from International Energy Agency “The center of gravity of global energy demand moves decisively towards emerging economies – they account for more than 90% of net energy demand growth to 2035.” (IEA) This led us to a conclusion that it is a fact that world is going to face the complex challenges in energy sector, especially developing countries that experiencing expand of population this will demand another billions of population and moreover as country developed their living standard will be improve which will more intensify the problem of the lack of energy demands. On top of that, meanwhile the supplies of conventional oil and conventional gas are expecting to be declined in near future (OECD) Meeting those challenges might require changes in fundamental issues such as changing patterns of energy production, consumption, policies and son.

...m fossil fuels, there remains alternative resources that can easily be taken advantage of. So why isn’t the United States taking this deeply into consideration and improving this dilemma? The energy crisis of the 1970’s continues on into the present as Americans search for new ways to fuel the consumption. This remains unresolved.
Semantically fossil fuels are a renewable source of energy, however given that it takes millions of years for the organic materials to be broken down and converted, it is wholly unrealistic to consider them as renewable. As the demand for fossil fuels increases and source diminish faster than they are replentished, the United States must work towards a renewable energy independent state using truly renable sources, both technically and in practice. With changes in the home, as consumers in buying goods and with alternative fuel sources backed by public trust and governmental involvement, the United States could drastically lessen its dependence on fossil fuels, foreign and domestic.

As the global population increases exponentially, having passed six billion in 1999, the world population is expected to be 8.9 billion by the year 2050. The worlds energy consumption will increase by an estimated 54 percent by 2025. Energy demand in the industrialized world is projected to grow 1.2 percent per year. Energy is a critical component of sustained economic growth and improved standards of living. One of the major requirements for sustaining human progress is an adequate source of energy. As the world’s technological enhancements and standards of living improve, so too does their appetite for electricity.

The human population growth rate is an alarming issue that brings with it irreversible consequences, that will likely effect the way of life for future generations to come. With the serious incline in population statistics comes catastrophic processes such as global warming and deforestation that have major ‘knock on’ ramifications. It’s issues such as these that need to be considered when we think about the growth of the human population, and we must take into account why these issues are occurring. We must also explore the options available to us that may assist in limiting the problems, or eliminating them all together, to provide a better place, not only for us in existence now, but also those who will walk this earth in the future decades and centuries to come.
According to the US Environmental Protection Agency, over half of the oil used in the USA is imported. Most of this imported oil is located in the middle east and is controlled by OPEC members. Subsequent oil price shocks and price manipulation by OPEC have cost our economy dearly—about $1.9 trillion from 2004 to 2008—and each major shock was followed by a recession (Reduce). We may never be able to fully eliminate our need to import oil, but we can reduce cartel market control and the economic impact of price shocks by reducing our demand (Reduce). One way we can reduce our reliance on oil is through investing in renewable energy. Solar power, wind power, and hydro power are all forms of energy which come from renewable resources. Unlike oil, solar, wind and hydro electric power is abundant and can be obtained locally.
Alternative energy sources are renewable, and is most commonly referred to as free energy sources. There are many alternative energy sources such as hydro power, solar power, wind, biomass, and geothermal. Using alternative sources is more expensive in the long run, but it is the much safer option for our environment compared to fossil fuels. Although everything used is completely free, such as water and wind, the equipment used to generate these things are expensive. There are several pros and cons that come with the utilization of alternative energy sources.
This book has given a new scientific understanding of these issues. and their problems by exploring a holistic view of life and all of its components. The. As Capra terms it, "a new vision of reality. " The world is becoming intertwined economically with the world.
The present world with its sustainable resources, environment and way of life became developed. The population growth, consuming almost all the available resources, to meet people’s needs, should be a major concern. The consumption of material and energy around the world which is about to eliminate the available supply, has increased over the last two decades, especially in the built environment. In order to access other reserves of fuel, the more energy will be needed to use.

Energy Efficiency refers to the use of energy on the same level, performance, comfort, suitability. As the world progress through technologies, more energy is required to power the world through various sources. Society has reached a point of our civilization when electricity is used for all purposes and therefore our presence will be impossible without it. However increasing amount of energy used will lead to numerous social and economic problems. Electricity demand is increasing twice as fast as overall energy use and is likely to rise by more than two-thirds 2011 to 2035. In 2012, 42% of primary energy used was converted into electricity. In the near future, cities will need to become increasingly energy efficient to deal with them. There are three strategies to attain energy efficiency which have their benefits.
One of the most complex issues in the world today concerns human population. The number of people living off the earth’s resources and stressing its ecosystem has doubled in just forty years. In 1960 there were 3 billion of us; today there are 6 billion. We have no idea what maximum number of people the earth will support. Therefore, the very first question that comes into people’s mind is that are there enough food for all of us in the future? There is no answer for that. Food shortage has become a serious problem among many countries around the world. There are many different reasons why people are starving all over the world. The lack of economic justice and water shortages are just merely two examples out of them all.
