The mass is no longer satisfied with products manufactured, but tends to customize products according to respective demands.
The decreasing amount of fossil fuels and an increasing demand for energy at the same time immediately suggest the improvement of energy efficiency. Existing technologies allow us to substantially reduce greenhouse gases in the U.S. by increasing energy efficiency, which leads to sustainable use of resources. Furthermore intelligent solutions can provide ecological benefits as well as economic advantages.
Essential for the efficient use of energy is the development of electromobility as well as a smart grid and smart building. Sustainability and energy efficiency can be achieved by the interaction of renewable energy, electromobility, efficient power plants and households, which act as so called 'prosumers', meaning that households produce more energy, than they need, for example by the use of solar panels.
Electric cars on the other hand do not only consume electric power but can also provide mobile storage in times of high electricity generation from renewable sources, like high wind or sunshine. In times of high demand for energy the surplus stored in electric vehicles can be fed back into the smart grid, an intelligent technology which improves the efficiency on the power network and in the homes and businesses of energy users.
Power network is under revolution, so does the power generators. People would have never thought of applying solar energy to their households and businesses decades ago. Nowadays however, the solar energy usage can be widely seen in a broad range of green products, typically the garden lights, green street lamp, or street lights (Supera60 alike). Specifically, the mass is no longer satisfied with products manufactured, but tends to customize products according to respective demands. To this extent, production of one products involves not merely manufactuers, but also the consumers.
By renewable energy, wind, solar and hydro technology, we can tap into unlimited natural energy sources to meet the world's growing energy needs. However it is as well important to transport the energy to where it is needed with as little loss as possible. The transfer of power by a high-voltage direct current (HVDC) transmission system allows the efficient transport of power over large distances. HVDC minimizes power losses and line costs of overhead lines for distances longer than 600 kilometers.
What this all amounts to is that the system of energy and power is becoming more complex. While some decades ago power was only generated by a relatively small number of power plants and heat plants, in some years millions of households and electric vehicles will be part of the smart grid. By integrating electric vehicles into the smart grid, they become a part of the energy system instead of simply consuming energy. During peak power generation times - for example periods of strong wind or intense sunshine - electric vehicles store energy which is returned to the grid in times of high demand. The same will apply for households and businesses. Instead of simply consuming energy, they will be 'prosumers', meaning consumers and producers at the same time.
