Science (New York, N.Y.)
|July 4, 1980
Resumen
La demanda mundial de energía aumentará significativamente en los próximos 50 años, lo que requerirá un cambio a combustibles fósiles de menor calidad. La adaptación de la infraestructura energética presenta desafíos, junto con preocupaciones ambientales y geopolíticas.
Área de la Ciencia:
- Análisis de sistemas energéticos Análisis de sistemas energéticos
- Estudios Ambientales Globales Estudios Ambientales Globales
- Gestión de Recursos Gestión de Recursos
Sus antecedentes:
- Los estudios existentes de oferta y demanda de energía a menudo pasan por alto las interdependencias globales y los ajustes a largo plazo necesarios para las nuevas fuentes de energía.
- Es necesario un análisis global exhaustivo para comprender los futuros balances energéticos.
Objetivo del estudio:
- Analizar el balance global de la oferta y la demanda de energía para los próximos 50 años en siete grandes regiones del mundo.
- Evaluar dos escenarios de referencia para el consumo futuro de energía y la disponibilidad de recursos.
Principales métodos:
- Modelado a escala global de la oferta y la demanda de energía.
- Análisis de dos escenarios distintos: una proyección de consumo de energía "baja" y una "alta".
- Evaluación de la disponibilidad de recursos, los plazos de adaptación de la infraestructura y los impactos ambientales.
Principales resultados:
- Se prevé que el consumo mundial de energía aumente de 8.2 teravatios por año a 22 teravatios por año (escenario bajo) o 35 teravatios por año (escenario alto) para 2030.
- El tiempo se identifica como la principal restricción para la adaptación de la infraestructura de suministro de energía.
- Es necesario un cambio significativo hacia combustibles fósiles de baja calidad (petróleo de esquisto, arenas bituminosas).
- Se anticipan mayores desafíos ambientales y geopolíticos debido a la dependencia de los combustibles fósiles y la distribución de los recursos.
Conclusiones:
- El panorama energético global se enfrenta a un crecimiento sustancial de la demanda durante el próximo medio siglo.
- La transición a nuevas fuentes de energía e infraestructura estará limitada por el tiempo, lo que requerirá una dependencia de combustibles fósiles de menor calidad.
- Las futuras estrategias energéticas deben abordar los significativos riesgos ambientales y geopolíticos asociados con la utilización de los recursos.

01:14Energy Diagrams - I
The dynamics of a mechanical system can be easily understood by interpreting a potential energy diagram. Since energy is a scalar quantity, the interpretation of the dynamics of the system becomes even simpler.
Take the example of a skater on a parabolic ramp. The potential energy at different points along the ramp will be proportional to the height of the ramp, which varies quadratically with the horizontal position on the ramp. As the skater moves down the ramp from the highest position,...

01:10Energy Diagrams - II
Energy diagrams are important to understand the dynamics of a system. The topology of an energy diagram helps illustrate the equilibrium points of the system.
The point in the energy diagram at which the system’s potential energy is the lowest is known as the local minima. The system tends to stay in this position indefinitely unless acted upon by a net force. The slope of the potential energy diagram at the local minima is zero, indicating that zero net force is acting on the system. The slope...

04:10What is Energy?
The universe is composed of matter in different forms, and all forms of matter contain energy. The different forms of energy on Earth originate from the Sun — the ultimate energy source. Plants capture light energy from the Sun, and, via the process of photosynthesis, convert it into chemical energy. This stored energy from plants can be harnessed in many ways. For example, eating plant products as food provides energy for our body to function, and burning wood or coal (fossilized plants)...

01:12Power and Energy
The power and energy delivered to an element are subjects of great significance in the field of electrical engineering. It is a well-known fact that a 100-watt light bulb emits more light than a 60-watt one. Therefore, power and energy calculations play a crucial role in the analysis of electrical circuits.
Power, defined as the time rate of expending or absorbing energy, is quantified in units called watts (W). The relation between power and energy is mathematically given as
