Why should we be doing everything possible to develop geothermal energy technologies.

The main reason is that this is a largely untapped area of tremendous alternative energy potential, as it simply taps the energy being naturally produced by the Earth herself. Massive amounts of power are present below the surface crust on which we move and have our being and basically all we need do is tap into it and harness it.

At the Earths’ core, the temperature is 60 times greater than that of water being boiled. The tremendous heat creates pressures that exert themselves only a couple of miles below us, and these pressures contain huge amounts of energy.

Superheated fluids in the form of magma, which we see the power and energy of whenever there is a volcanic eruption, await our tapping. These fluids also trickle to the surface as steam and emerge from vents. We can create our own vents, and we can create out own containment chambers for the magma and convert all of this energy into electricity to light and heat our homes.geothermal energy

In the creation of a geothermal power plant, a well would be dug where there is a good source of magma or heated fluid. Piping would be fitted down into the source, and the fluids forced to the surface to produce the needed steam. The steam would turn a turbine engine, which would generate the electricity.

There are criticisms of geothermal energy tapping which prevent its being implemented on the large scale which it should be. Critics say that study and research to find a resourceful area is too costly and takes up too much time. Then there is more great expense needed to build a geothermal power plant, and there is no promise of the plant turning a profit.

Some geothermal sites, once tapped, might be found to not produce a large enough amount of steam for the power plant to be viable or reliable. And we hear from the environmentalists who worry that bringing up magma can bring up potentially harmful materials along with it.

However, the great benefits of geothermal energy would subsume these criticisms if only we would explore it more. The fact that geothermal power is merely the energy of the Earth herself means it does not produce any pollutants.

Geothermal energy is extremely efficient—the efforts needed to channel it are minimal after a site is found and a plant is set up. Geothermal plants, furthermore, do not need to be as large as electrical plants, giant dams, or atomic energy facilities—the environment would thus be less disrupted. And, needless to say, it is an alternative form of energy—using it would mean we become that much less dependent on oil and coal.

Probably most importantly of all—we are never, going to run out of geothermal energy, and it is not a commodity that would continuously become more expensive in terms of real money as time passes, since it is ubiquitous.

Geothermal energy would be, in the end, very cheap, after investigation and power plant building costs are recouped.

It seems that Japan have a new outlook on renewable energy with the new, ‘hydrangea solar cell’.

A solar cell that resembles a flower is offering a new take on green energy in Japan, where one scientist is searching for renewable energy that looks good.

In a country badly scarred by the tsunami-sparked nuclear disaster at Fukushima three years ago, the hydrangea-inspired solar offering is small beer alongside one of the world’s biggest offshore wind power farms now floating off the country’s east coast.

But Hiroshi Segawa, a professor at University of Tokyo’s Research Centre for Advanced Science and Technology, is hoping his dye-sensitised solar cell, which meshes floral beauty with cutting-edge technology, will brighten the scene.

Segawa’s Annabelle, named after a type of white hydrangea, is made up of flowery stained glass-like solar cells built into a latticed wood box modelled on traditional Japanese doors.

While the 20 centimetre (8 inch) wide box might make a pretty addition to a sunroom, it can also store enough energy to charge your smartphone twice.

The leaves generate electricity, which is stored in the flower. As the device charges up the petals turn increasingly blue. But as Annabelle discharges, those blue petals turn white, just like the real-life hydrangea.

‘Enjoyable energy’

“People do not have a very good image about things related to energy, such as nuclear power,” Segawa told AFP.

“Thermal power generation conjures up images of blistering hot dirty coal while solar panels take up a lot of space.

“Even wind power generation has problems with bird strikes and noise, but (Annabelle) doesn’t harm the environment.”

While Segawa is not expecting to topple the dominant silicon-based solar panels, he is hoping the fast-growing sector has room for “enjoyable energy” that adds a splash of colour to an otherwise drab industry.

Since the Fukushima nuclear disaster in 2011, Japan has been pushing to boost the use of alternative energy.

The country’s solar power generation is rapidly growing, but it still only represents a small share of the overall power mix.

In Japan, the share of power generated from renewable sources, excluding hydropower lags other developed economies at 4.7 percent of the total, far less than 10.4 percent in Britain or 20.1 percent in Germany, according to data from the International Energy Agency.

All of Japan’s nuclear plants were shuttered after the 2011 atomic accident — taking away a power source that once supplied more than one-quarter of the nation’s energy.

Despite Tokyo’s efforts to develop the solar sector, the weather —- particularly a lack of reliable sunlight — is among the factors holding back wider use.

But Segawa says Annabelle works even in weak indoor light.

It also has a myriad of design possibilities. Segawa has already experimented with a cell that looks like French President Francois Hollande and one of the computer-generated Japanese pop star Hatsune Miku.

“You can make solar cells out of animated characters, portraits of real people and lots of other stuff,” he said.
