Tidal Power in UK is Promising

- Adam Clare

The UK is looking into ways to make their power grid more environmentally sustainable and being an island nation they have looked into using tides. Tidal flows are predictable and reliable which means that power companies can predict energy generated from tide-powered turbines, unlike with unpredictable wind. A new study reveals that the latent energy in tides can be used to supply a lot of the nations electric needs.

“From tidal barrages you can reasonably expect you can get 15% of UK electricity needs, that’s a very solid number,” co-author Dr Nicholas Yates from the National Oceanography Centre told BBC News.

“On top of that there is a 5% tidal stream figure, and with future technological development that is likely to be an underestimate in my view,” he said.

Urban Density Decreases Car Use

It’s well established that people living in urban areas use cars less frequently than their suburban and rural counterparts. Some argue that it is thanks to better transit services that urbanites don’t drive but there is another reason for success. Population density alone can make a striking impact on how often people drive!

Holtzclaw concluded that even in areas with minimal transit service, density affected VMT [vehicle miles travelled]. For example, in an area with only two buses per hour, a census tract with 20 households per acre drove about 40 percent less per household than one with two units per acre (15,374 per year as opposed to 27,339). But VMT did not stop dropping at the 20 households per acre level. An area with 100 households per acre drove 1/3 fewer miles than the 20-per-acre neighborhood (10,028 VMT per household) and one with 500 households per acre drove 40 percent less than the area witih 100 households per acre (5781).

Social Media Helps Global Development

- Adam Clare

Social media can actually be useful for more than sharing pictures of your lunch! There is a whole collection of apps and web services that can be used to help development efforts around the world. They provide the ability to track how projects are coming along and their current status to being able to connect farmers to more information and their own local social networks.

My favourite service is one that allows people to report corruption:

I Paid a Bribe is an anticorruption movement that harnesses the power of collective voices. Protected by anonymity, users are encouraged to report on corrupt acts, through a website, email or SMS. The reports are mapped on the site and used to inform campaigns for better governance. The movement is active in India, Greece, Kenya, Pakistan and Zimbabwe, after its founder, Tawanda Kembo, was pressured to pay a bribe by a corrupt police officer, and will be coming soon to the Philippines and Mongolia.

In Ireland, Carbon Tax Means Less Waste and More Revenue

- Adam Clare

Modern economies indirectly subsidize environmentally damaging corporate practices by ignoring the environmental costs ( younger generations have to deal with the environmental damage), this can be seen in everything from the tar sands in Alberta to ewaste in electronics. In Ireland they have started a carbon tax to deal with this environmental problem while raising a lot more revenue for the country.

The results in Ireland prove promising and may encourage other countries in Europe to take the European Commission’s suggestions that a carbon tax can help other debt-ridden economies.

Household trash is weighed at the curb, and residents are billed for anything that is not being recycled.The Irish now pay purchase taxes on new cars and yearly registration fees that rise steeply in proportion to the vehicle’s emissions. Environmentally and economically, the new taxes have delivered results. Long one of Europe’s highest per-capita producers of greenhouse gases, with levels nearing those of the United States, Ireland has seen its emissions drop more than 15 per cent since 2008.
…
The three-year-old carbon tax has raised nearly 1 billion euros ($1.3 billion) overall, including 400 million euros in 2012. That provided the Irish government with 25 per cent of the 1.6 billion euros in new tax revenue it needed to narrow its budget gap this year and avert a rise in income tax rates.
