Hydroelectricity

 

Hydro-electricity is presently the largest contributor to renewable energy worldwide; in Australia and particularly in NSW.

 

Hydro-electricity also is more desirable than wind generation because of a higher capacity factor and ability to produce power on demand.

 

But hydro-electricity is resource constrained as it is difficult to build new dams in the developed countries that are presently heavy fossil fuel consumers.

Dams flood private property and/or National parks and have many self-interested and environmentally concerned opponents.  Hydro-electric schemes interfere with natural river flows and related wildlife, particularly when they involve extensive inundation.  It has become politically very difficult to construct new dams in Australia, even when the potential energy resource is significant. 

Nevertheless in developing countries like China, India and Vietnam there are large hydro-electricity resources that remain unexploited.

The United States of America – East Coast

 

 

In the late seventies I lived and worked in New York.  My job took me all around the United States and Canada.  So I like to go back occasionally; the last time being a couple of years ago with my soon to be wife Wendy.  She had never been to New York so I worked up an itinerary to show her the highlights in just a few days.  We also decided to drive to Washington DC and Boston.

The Soul of the Matter

 

 

 

 

It was hot, dry and dusty when they finally arrived in Jaisalmer.  But then, how often is it not hot and dusty here? 

In the markets a wizened woman, of indeterminate age, is using a straw broom to aggressively sweep the area in front of her shop. The dust will soon be kicked-back by passers-by; or swept back by her neighbours; requiring her to sweep again, and again.  She will do the same again tomorrow; and the day after; and the day after that.

Jennifer's mind is elsewhere. She's has dreamt of visiting exotic India ever since a client at the hairdressers told her, with enthralling details, of her adventures here.

They've arrived in the dusty city late in the afternoon, by road from Jodhpur.  In spite of his preference to visit California or Las Vegas again, she's finally persuaded Bruce that he might like India. He should try something a bit more adventurous for a change.

Below the entrance to the famous Jaisalmer Fort, is a small square that marks the start of the road winding up, then turning at right-angles, through the protective elephant-proof gates.  In this little square, motorised trishaws: Tuk-tuks, jostle restlessly like milling cattle.  They are waiting for tourists, like our travellers, who may hire them tomorrow to see the town or, if they are lazy or tired, just to mount the steep hill up to the Fort.

Energy Solutions

 

Most informed commentators agree that Australia needs a better mix of energy sources.  We are too dependent on fossil fuel.  This results in a very high rate of carbon dioxide production per capita; and this has international and domestic implications in the context of concerns about climate change.
