Building sustainable cities: A challenge

A city may be favored for its rich history, significant contributions, or picturesque skyline, but what if they’re not sustainable? We can do better! There are ways cities can go from gas-guzzling to green, and some of the options are actually quite simple. The following graphics explains the same.

Transportation and Sustainable Vehicles

Consider a conversion to electric vehicles. These vehicles are becoming more popular among consumers, and rising gas costs are helping to build that popularity. Electric cars can use 40-60% less petroleum than vehicles that run on gas,  saving millions of gallons over a span of years if you consider every electric vehicle being used. Electric vehicles have also saved 8,700 metric tons of CO2, effectively reducing the carbon footprints of cities across the nation. Adding better mass transit options- such as improved bus lines- can encourage city dwellers to ditch their cars. Public transit saves gas and reduces CO2 emissions, and more and more people are taking the bus to avoid gas costs or go green.

Green Architecture and Sustainable Buildings

For new buildings, living architecture can be a great option for cities wanting to go green.  Buildings are constructed using biomaterials, saving trees. Buildings in U.S. cities currently occupy 65% of electricity consumption, 30% of greenhouse gas emissions, and 30% of raw materials use. A city using this kind of building method can also enjoy a unique cityscape as they blaze a trail to a sustainable city. Existing buildings have plenty of options as well. A switch from heating oil to using natural gas can reduce CO2 emissions. Top off buildings with green roofs in order to reduce temperature and pollution while improving the city’s look. Green roofs help reduce temperature-control costs, can catch rainfall for use, and reduce runoff by 50-60%.

City Management and Smart Resource Control

The addition of wireless sensor networks can turn wasteful cities into sustainable cities through area monitoring. Temperature, pollution, water systems, waste management systems, radiation, traffic, and other components can be monitored for in efficiency. These systems can help detect leaks and problem areas quickly, potentially saving electricity and other precious resources. In order to save additional resources, cities can consider grassroots initiatives, like farmer’s markets and community-supported agriculture. Urban farming is a simple change, since dirt beds can be put nearly anywhere and grow food locally. Organizing community carpools and encouraging people to recycle waste and use reusable bags for shopping can make huge impacts as well. A staggering 75% of solid waste is recyclable, but steps need to be made to encourage more recycling to happen, as 70% is still thrown into the trash.

Cities can also become more sustainable and beautiful by adding open space. Hiking trails, activity centers, and parks can draw people into the city and reduce waste. Imagine the positive impact if all of our cities made more of these changes. Sustainable cities are the way of the future!

Effects of Lack of Volatility in Digital Currencies like Bitcoin

For forex investors, the last one year has been very disappointing. Everybody was anticipating some movements in the currency, which did not happen. The trading strategies have not come handy and it’s been a disappointing year so far. The level of volatility has been at its peak and in the last one year it has increased further.

Experts, Including those from Forex Bonus, tout many reasons for such a dry spell. But the one primary reason in which the market has underperformed is because of the continuous downgradation of interest level by central banks of most advanced economies. The reason of such act has been to keep risk levels at bay, while ensuring a steady growth.

Bitcoin, however, has been different from other digital commodities. The lack of governance from other governments sets it apart. The change in interest rate as well as economic recovery has no role in the bitcoin market. The recent political tension of America, Middle East, Israel and other countries will have very minimum effect on the bitcoin market.

This is the reason why bitcon market has been very productive. The last one year saw the bitcoin valuation going up by quite a high level. It went to a maximum level of 1,000. Experts believe that it will enjoy its growth before levelling at between 500 and 600. While such spikes and fall cannot be termed as steady, but it is a not a volatile market yet when compared to other commodities such as the currency market.

Bitcoin got its boost when the senate committee expressed concern over its legitimacy and the huge fall of Mt Gox. These two factors ensured that the price of bitcoins is on the high and it kept getting higher thanks to some government’s effort of making the currency legitimate.

However, there are several factors, which can be explained and related to bitcoins. As the more advanced economies make it non legit, more and more investors are going to lean on this instrument due to its high interest rate and quick return. Bitcoin, however, remains a very volatile instrument, but attractive nevertheless.

Until the advanced economies take a final call on the legitimacy of the bitcoin, the price of this commodity will be difficult to predict. Random fluctuations will continue. That being said, the current indecisiveness of the advanced economies is good for the overall bitcoin market because this will only ensure that the market goes up without any correction what so ever.

Traders these days are apprehensive and are making the hard choice of diversifying their portfolios and mitigating risks. The liquid forex market is not assisting the cause of the investors either. At the moment, the volatile market of several countries is making the investors invest in bitcoins because of the reasons mentioned above.

The fate of bitcoin, however, could change dramatically should there be any announcement by any advance economy. As experts have predicted since a long time, a correction is expected in the bitcoin market.
