This article shows some new good technologies or products
but I didn’t focus on other articles but only last one. The last article shows
how we can use the solar power differently. The normal solar energy gathers the
solar with the cell but this technology is different that it uses other materials
which are not that expensive. With using this, developing countries can have
massive opportunities that they can use hot water without needs of electricity.
One Africa country is already using it and the maker want to show that how good
green energy is.
TrustPower, the utility controlled by Infratil, wants to raise as much as $125 million of bonds and roll over existing debt to repay maturing bonds and for working capital.The electricity generator and retailer is considering a $75 million public bond offer, with the ability to accept a further $50 million in oversubscriptions, and will seek to roll over as much as $75 million of debt maturing in September
This article shows conversation between interviewer and Dr Wayne Campbell showing that problems of using solar power energy and why this one is so important to us. Especially, it is also telling us that why Grätzel solar cell is important to us. One of the problems to use is because the cell or silicon is expensive and the battery that we use for the night should have more capacity as sun is shining only during the day time.
After Japan had
triple disaster including nuclear accident nearby Fukushima, it paves way for
new geothermal plants. Fukushima people also need electiricity which was
covered by the nuclear electricity but geothermal plants will be the new answer
for that and it will be built inside a national park. It shows importance of
renewable energy with green energy.
This article shows the negative situation of hydrogen cars
for now. It said to have hydrogen cars on public, people should be able to refuelling
from the gas stations or at least they should have places for that but to build
those stations cost a lot. There for it is not easy to have hydrogen cars as commercialized
car. Obama administration also looks at the cold view to this idea and some of
important people already resigned. Another problem is that LPG is cheap and
already commercialized and has competitiveness. The hydrogen system should have
more competitiveness compare with other alternative resources. Otherwise it
might be take off even though it is good alternative resources and
technologies.
This article said we could have hydrogen energy from sewage.
In California, already trying to do this project and 25 car owners have been
filling up with hydrogen produced from excess methane. Cars with fuel cells convert hydrogen into electricity to turn a motor, and
potentially offer zero emissions, depending on the original fuel source. As
well as sewage gas, it is also possible to produce hydrogen from wind and solar
energy. But, sewage is preferable because it offers higher efficiency. Other car companies making fuel-cell cars and
only few companies doing research about making hydrogen cars but the Orange County Sanitation District project is showing
the manufacturers involved that hydrogen does have immediate prospects, and
that building a hydrogen fueling infrastructure may not be as expensive as
feared. Most of all, It doesn’t have
greenhouse emissions, it doesn’t have particulate emissions, and it doesn’t
depend on foreign imports. It’s a holistic solution.
This article shows that
the other way of making biofuel with milk in New Zealand. Gull's Force
10 biofuel is a blend of premium gasoline containing 10 per cent ethanol
produced by dairy cooperative Fonterra. Biofuel is any fuel derived from
biomass, recently living organisms or their metabolic by products, such as
manure, forest or crop waste, or even pond scum. In February the Government set
a national target of 3.4 per cent for the biofuel component of petrol and
diesel in 2012. Oil companies will have to start offering biofuels from April 1
next year, and the Government has said there will be no excise tax charged on
the ethanol. Gull was responding to public demands for better choice in the
retail fuel sector. The Force 10 blend will be included in the Progressive
Enterprises supermarket chains' discounts on fuel purchases.
This article shows that Wind
technologies are expected to supply 20% of New Zealand’s electricity by 2030,
according to a new report. The country’s Government has also aimed for 90% of
the energy to be generated from renewables by 2025. It expected increase
of wind power generation in the nation by 2030 – from 622MW to at least 3,500MW
– providing more than 1,500 jobs.

In the article, it took Raphael
Domjan an impressive 584 days to travel 30,000 nautical miles around the world.
According to the electrical engineer he didn’t make the trip to get into the
Guiness Book of Records, instead he wanted to do something about climate change
and show what one can achieve with solar power. Most of boats will use
this solar system near future except heavy ships like cargo ship.
