Read the following passage about smart energy and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

SMART ENERGY

The upcoming decades will bring significant changes in energy supply and consumption. As some major oil-producing countries have already reached 'peak oil' and concerns about global warming rise, many nations are prioritizing the transition to a low-carbon economy, which will transform electricity supply and usage. [I] Firstly, there will be an increase in overall demand, as consumers switch from oil and gas to electricity to power their homes and vehicles. [II] Secondly, there will be an increase in power generation, not only in terms of how much is generated, but also how it is generated, as there is growing electricity generation from renewable sources. [III] To meet these challenges, countries are investing in Smart Grid technology. [IV] This system aims to provide the electricity industry with a better understanding of power generation and demand, and to use this information to create a more efficient power network.

Smart meters can be integrated with the internet or telephone networks. This connectivity enables customers to control their appliances from a distance. For instance, individuals can turn devices on or off remotely, providing added convenience. Overall, the system offers significant benefits in managing energy usage. By analyzing real-time data, it allows for better decision-making. This technology not only improves efficiency but also supports cost savings. Ultimately, the integration of smart technology will enhance user experience and system management.

The coming decades will bring significant shifts in energy supply and usage. A problem is the fact that many renewable power generation sources are located in remote areas, such as windy uplands and coastal regions, where there is currently a lack of electrical infrastructure. New infrastructures therefore must be built. Thankfully, with improved smart technology, this can be done more efficiently by reducing the reinforcement or construction costs.

Although Smart Technology is still in its infancy, pilot schemes to promote and test it are already underway. Consumers are currently testing the new smart meters which can be used in their homes to manage electricity use. There are also a number of demonstrations being planned to show how the smart technology could practically work, and trials are in place to test the new electrical infrastructure. It is here where Smart Technology is likely to be promoted first, utilising a range of sustainable power sources, transport solutions and an infrastructure for charging electrically powered vehicles. The infrastructure is already changing fast.

Which of the following is NOT a benefit of Smart Grid technology to consumers?
