Impact: The project has a generating capacity of 21 megawatts and will be supported by a giant battery bank able to deliver 11 megawatts of power. Adding storage to renewable energy generation is more commercially viable in Hawaii because it has the highest electricity prices in the U.S.

Impact: The Amsterdam harbor for river cruisers and inland cargo vessels is located next to the city centre. Normally when the vessels are moored, the energy is generated by noisy on board diesel generators that emit exhaust gases, including CO2 emissions. The CO2 emissions from the used renewable energy are minimal.

Impact: IWW brings together businesses, non-profit organizations, government agencies and scientists to explore practical solutions to various global water issues.

Impact: DUALdrive is highly efficient (90%) over a wide power range and has maximum power available over wide LED voltage and LED current range. It also allows accurate control of color temperature, which has been proven to have a profound effect on our sense of wellbeing.

The proportion of scattered light – which is diffused into the environment – is considerably reduced, and light pollution – which is diffused into the night skies – is avoided. Only the defined area is actually illuminated. One of the other advantages include the numerous possibilities of lighting control with which the light flux can be dimmed via infinitely variable control and, thus, ideally adjusted to suit the prevailing requirements.

Impact: This technology achieves more than a 70% reduction of the energy consumption and CO₂ emissions, while still producing the same technical light results and agreeing with all safety regulations. The maintenance costs are considerably lower.

Impact: The company’s high efficiency and high performance systems provide the lowest levelized cost of energy (LCOE) in high sun regions and very little space is needed for this.

O sistema inteiro é feito de células de silício fotovoltaico à prova d’água e durável o suficiente para resistir a condições climáticas desfavoráveis, ​​que funciona como uma lente que concentra a luz nas células solares com uma eficiência ideal.

O concentrador foca a radiação incidente sobre o fotodiodo colocado em um ponto, que de acordo com a física, será o foco fundamental. Toda a planta solar será na forma de uma enorme balsa que irá flutuar sobre a água.

O projeto visa o desenvolvimento de uma fazenda solar em locais como oceanos, represas, lagos entre outros. Considerando as limitações tecnológicas do momento, a fazenda flutuante será desenvolvida em conjunto com usinas hidrelétricas, para complementar a sua produção de energética.

Uma vez que os corpos d’água, como oceanos, lagos e represas recebem luz solar direta, sem problemas causados pelo sombreamento, as células solares seriam mais ativas e capazes de produzir mais eletricidade.

Durante as condições de tempo favoráveis, este concentrador converte toda a radiação incidente em força eletromotiva (EMF). Quando o tempo estiver muito ruim, ela simplesmente submerge e depois surge novamente na superfície da água, como uma boia,quando o tempo tornar-se favorável. Por isso, é um sistema altamente econômico, que requer manutenção técnica mínima.

The new ZDEP component (Near Zero Discharge/Extra Production) is a productive, efficient, sustainable and dependable aquaponic system to produce fresh fish and a variety of vegetables, all on one integrated system, with no waste.

Impact: The ZDEP system by Nelson and Pade almost doubles the vegetable production and nearly all water and waste from the system can be fully used, reducing or eliminating discharge.

The Council invests into renewable energy through the “Building Regulations” drawn up in 2010, which establish that new public and private buildings have to cover the 25% of total energy requirements of the building or not less than 50 % of energy requirements for the production of hot water, through the use of renewable sources.

Impact: Bruneck serves as an example, to be followed by other cities. It can guarantee high savings on the cost of powering homes and businesses.

Impact: Going Green helps people to understand the impact of key environmental and human issues worldwide. The series of specials are engaging viewers around the world through important messages of conservation and hope.
