What You'll Learn
Electricity improves quality of life
Electricity is an essential part of modern life and significantly improves our quality of life in several ways.
Firstly, electricity provides heating, cooling, and lighting for homes, schools, and healthcare facilities. For example, in healthcare, electricity is required to refrigerate vaccines, sterilize equipment, and provide lighting for emergency procedures. Similarly, schools need electricity for heating, cooling, and lighting to provide a space for students to study after dark. Electricity also enables the use of modern heating systems, such as infrared radiant heaters, convection heaters, and heat pumps, which are more efficient and environmentally friendly than traditional heating methods.
Secondly, electricity powers devices and appliances that enhance our daily lives and boost productivity. These include computers, medical equipment, electric stoves, and air conditioning. Electricity also enables the use of modern means of transportation, such as electric trains and cars, which are quicker and more environmentally friendly than traditional modes of transport.
Thirdly, electricity contributes to economic growth and the enhancement of production processes. Businesses rely on electricity to power machinery, communications technologies, and lighting. Electricity also lowers the cost of goods by enabling the use of innovative, energy-efficient technologies and moderating energy consumption.
Lastly, electricity powers essential services such as public transportation systems and hospitals. It also facilitates access to information and entertainment through the use of electronic devices and the internet, although this is often dependent on a reliable electricity supply.
In conclusion, electricity is integral to modern life and significantly enhances our quality of life by providing heating, lighting, and power for essential devices, services, and economic activities.

It powers modern transportation
Electricity is integral to modern transportation systems. It powers public mass transit systems such as trains, subways, and trams, as well as electric vehicles (EVs) that are growing in popularity.
Electric vehicles, including battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs), use electricity stored in on-board battery packs to power the electric motor and move the vehicle. BEVs rely solely on electricity for all power needs, while PHEVs can use either the electric motor or an internal combustion engine. The electric motor improves fuel economy by using a smaller internal combustion engine, powering auxiliary loads, and powering the vehicle at stops or low speeds. The battery is charged by the engine and regenerative braking, capturing energy normally lost during braking.
The adoption of electric vehicles is significant for reducing carbon emissions. In 2022, sales of electric cars surpassed 10 million, and their growth is propelled by concerns about environmental impacts and investments from the private sector and government agencies. Electric vehicles are particularly suitable for urban transportation due to shorter ranges and the availability of recharging stations.
While transportation is predominantly reliant on petroleum products, electricity plays an increasingly important role in powering modern transportation. The use of electricity in transportation contributes to a more sustainable future by reducing the consumption of fossil fuels and lowering carbon emissions.

It's essential for healthcare
Electricity is essential for powering modern life and is crucial for healthcare. It is needed to power critical and life-saving medical devices, as well as basic services such as lighting, communications, and clean water supply. Reliable electricity is essential for medical equipment necessary to safely manage childbirth, ensure immunization, and perform routine and emergency procedures.
The World Health Organization (WHO) has emphasized that electricity is a "critical enabler" of universal access to healthcare. Reliable basic infrastructure, especially electricity, is vital for improving health systems and achieving sustainable development goals. For example, reliable electricity increases the utilization of child immunization and maternal health services.
In low- and lower-middle-income countries in South Asia and sub-Saharan Africa, approximately 12% and 15% of healthcare facilities, respectively, have no access to electricity. In sub-Saharan Africa, only half of the hospitals have reliable electricity access. This lack of access disproportionately affects rural areas, with urban healthcare facilities often having better electricity access.
To address this issue, several clean and cost-effective energy solutions are available, such as solar photovoltaic systems, which can rapidly electrify healthcare facilities sustainably and increase their climate resiliency. Support, financing, and investments must be scaled up to accelerate healthcare facility electrification and improve access to reliable electricity, which is essential for providing quality healthcare services.

Electricity is needed for education
Electricity is an essential part of modern life, and its importance in education cannot be overstated.
Firstly, electricity provides basic amenities such as heating, cooling, and lighting, which are fundamental for creating a conducive learning environment for students. Schools with access to electricity can also stay open for longer, providing students with more time and space to study. This is especially crucial in regions with limited access to educational resources, such as textbooks and spacious classrooms. For example, in the Philippines, solar panels were installed in schools, eliminating the need to cancel classes on rainy days due to a lack of lighting.
Secondly, electricity enables access to information and communication technologies (ICT). In today's world, computers and the internet are invaluable tools for learning and teaching. They provide students and teachers with vast resources, facilitating research, interactive learning, and the acquisition of digital skills that are essential in the modern job market.
Thirdly, electricity is critical for the functioning of educational equipment and appliances. For instance, in science laboratories, electricity is required to power equipment and conduct experiments. In the arts, electricity is needed for musical instruments, art installations, and other creative pursuits.
Lastly, electricity is vital for the administrative aspects of education. It enables the use of computers and digital platforms for record-keeping, report card generation, and communication between teachers, students, and parents. It also facilitates the use of modern security systems, ensuring the safety of students and staff.
Despite these evident advantages, it is troubling that many schools worldwide still lack access to electricity. According to surveys, a significant number of primary and secondary schools in African countries and village schools in India are without electricity. This hinders not only the quality of education but also the potential for economic growth and poverty reduction within these communities.
In conclusion, electricity is vital for education as it provides the basic necessities for learning, enhances access to information and technology, and enables the use of essential equipment and administrative tools. Ensuring that all schools have access to electricity is a crucial step towards empowering students and creating a brighter future.
