Power In a previous part of Lesson 1it was said that work is done upon an object whenever a force acts upon it to cause it to be displaced.
Economic growth Using a neo-classical aggregate production model where capital, labour, technology, and energy are treated as separate inputs, this paper tests for the existence and direction of causality between output growth and electrical energy use in Barbados, analysed as a whole and in sectors respectively.
In addition, the evidence reveals a bidirectional causal relationship between electrical energy consumption and real GDP in the long run, but only a unidirectional causal relationship from energy to output in the short run.
Forecasts indicate increasing consumption of electrical energy, particularly by the residential sector. Changes in the regulatory environment will also be necessary if such plans materialise.
Policymakers will need to pay greater attention to the expected increase in the rate of consumption by the residential sector, as this will help to reduce the imports of oil and depletion of scarce foreign exchange resources by a sector that does not spur economic growth. An increase in energy capacity should be encouraged as contingency planning in the event of a technical or political disruption to fuel imports will be critical, notwithstanding the drive to use more renewable sources of energy.
Introduction Over the last four decades, the demand for energy in Barbados—a small developing country in the Caribbean—has grown, as it has pursued policies geared towards greater economic growth and social development.
First, there is the fact that Barbados, a net importer of not only energy, but food and other vital raw materials, has to devote a growing fraction of its foreign reserves to satisfy its demand for energy.
Against this background, the Government of Barbados has begun Importance of electrical energy place greater focus on energy conservation and renewable energy sources. It is important, therefore, to ascertain whether there is a casual link between energy and economic growth, given that any constraints placed on energy consumption would have an adverse effect on growth and development if causality runs from energy to GDP only.
Although the existence of a relationship between energy con- sumption and economic growth is now reasonably established in the literature, the direction of causation, that is, whether economic growth leads to energy consumption or energy consumption leads economic growth, remains an unsettled issue.
Four possible relationships have been emphasised in the literature between energy consumption and economic growth: Box 64, Bridgetown, Barbados.
On the other hand, a shortage of energy may negatively affect economic performance, leading to a fall in income and employment. If, instead, causality runs from economic growth to energy consumption and the relationship is positive, this implies that an economy is not energy-dependent and hence energy conservation policies may be implemented with no adverse effect on growth and employment Masih and Masih, The feedback hypothesis suggests that energy consumption and real GDP are interrelated and may very well serve as complements to each other.
Should this result hold, then shocks, positive or negative, to either one of these variables would have effects, possibly permanent, on the other.
Finally, if there is no causality in either direction—the neutrality hypothesis—this implies that changes in energy consumption are not associated with changes in GDP, so that energy conservation policies may be pursued without adversely affecting the economy Jumbe, However, Mahadevan and Asafu-Adjaye suggest that the use of electricity consumption see studies such as Jumbe, ; Shiu and Lam, ; Yoo, may be appropriate for economies which are heavily reliant on electricity for their energy.
Moreover, Ferguson et al. This paper thus aims to empirically investigate the causal association between electrical energy consumption and economic growth in Barbados. Electrical energy consumption will also be disaggregated into two sectors, residential and non-residential respectively, to assess their relationship with GDP.
Our empirical work is largely derived from the seminal contribution to the energy literature by Stern Stern's approach examined the relation- ship between energy and growth by considering the possibility that the relationship may include more complex interactions with capital and labour.
Within this context, we employ the techniques of multivariate cointegration, vector auto-regression VARcausality testing and innovation accounting. Finally, we forecast energy consumption within the framework of the VAR.
The remainder of this paper is organised as follows. Section 3 presents a select review of the pertinent empirical literature on electricity consumption and economic growth. Section 4 introduces the empirical model, econo- metric methodology and data sources used in this research paper.
Section 5 presents the results and analysis. Section 6 discusses the policy implications. Barbados' economy, which is services-driven mainly tourismgrew at an average of 2. Like other developing countries, Barbados has faced an electricity demand which has increased over time. In conjunction with economic growth, per capita consumption of electricity has steadily increased over the last few decades ranging from kW h in to kW h in Over this same period, electricity consumption grew an average of 3.
As indicated in Table 1, the largest single category of users is the residential sector, which accounted for one-third of total consumption in recent years. At present, the electricity sector in Barbados is a government-granted monopoly; only one company is involved in generation, distribution and transmission.
Electricity pricing is regulated by a government institution in an effort to shield customers from possible monopoly pricing by the sole provider.What Is Electrical Energy?
Energy is the ability to do work, where work is done when a force moves an object. We need and we use energy every day, and energy is available in all different forms. 1.
Introduction. The term ‘electrical energy storage’ encompasses a substantial number of diverse technologies whose aim is to store energy, with the aim of later releasing it in the form of electricity.

It is important to store electrical energy just as it is important to store any type of energy. Stored energy can be used as opposed to wasting it and therefore fewer resource s are needed to generate new energy..
Storing Electrical Energy is not as obvious as you would think.
